2. Introduction and Overview
Congratulations on your purchase of the OmniConnect/ISDN! The OmniConnect series of
access device offers an inexpensive, complete ISDN Internet access solution for the small or
branch office. The OmniConnect/ISDN is ideal for Small Office Branch Office (SOBO)
applications such as network-wide Internet access and making LAN-to-LAN connections to
remote nodes. The OmniConnect/ISDN access device connects Ethernet LANs to other
networks over Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) lines.
The OmniConnect/ISDN offers TCP/IP routing capability between LAN and WAN ports. In
addition, advanced services such as filtering, DHCP and NAT are available.
This chapter contains the following sections:
•Product features
•Security features
•Supported internet request for comments (RFCs)
•Internet access device front and back panels
•Physical specifications
2.1. Product features
This section describes the major features of the OmniConnect/ISDN device.
2.1.1. Hardware
The OmniConnect/ISDN access device features the following hardware interfaces:
•One ISDN U or S/T ISDN WAN Interface
•Four 10Base-T Ethernet LAN Ports
•One Plain Old Telephone System (POTS) analog port
•One nine pin (DB-9) serial console port
•One 2.5 mm DC (12V, 1A) power jack
The OmniConnect/ISDN access device also features nine status lights on the front panel to
provide visual indication of the access device operation. The access device itself can be
mounted on either a wall or desktop.
2.1.2. OmniStart
OmniConnect/ISDN remote access / Internet access device software includes OmniStart, a
Graphical User Interface (GUI) utility to assist the user in configuring the access device for
operation.
2.1.3. OmniConnect Monitor
OmniConnect/ISDN device software includes OmniConnect Monitor, a Graphical User
Interface (GUI) utility to assist the user in gathering statistics regarding the access device’s
operation after the configuration process is complete or while the access device is operating.
2.1.4. ISDN Basic Rate Interface (BRI)
OmniConnect/ISDN features either a standard U or S/T interface. (The OmniConnect/ISDN
(U) version uses the U interface and the OmniConnect/ISDN (ST) uses the S/T interface).

OmniConnect / ISDN User’s Manual Page 4
Part number 613-10787-00
Both interfaces support two independent Bearer (B) channels that can be connected to two
destinations or bundled for one connection to support Bandwidth-On-Demand. In addition to
standard data bearer services, the OmniConnect access devices support Data over Voice
(DOV) service. In some areas, DOV allows the use of inexpensive voice bearer services while
transmitting data, thus saving on long distance and other toll costs.
2.1.5. Advanced voice support
The OmniConnect series of remote access / Internet access devices feature built-in support for
voice call management. OmniConnect equips a small office with the communications
capabilities of a sophisticated corporate office. With OmniConnect/ISDN’s advanced voice
support, small office professionals will present the same professional image as their corporate
office counterparts. By leveraging the full power and speed of ISDN digital telephone service,
the OmniConnect access device provides comprehensive, cost-effective communications for a
small office - including complete voice and data call management. The flexible
OmniConnect/ISDN combines the capabilities of a personal phone system, personal assistant
and ISDN access device into a single, integrated and easy to use product.
OmniConnect/ISDN provides professional call management, call forwarding, distinctive
ringing and caller ID. OmniConnect forwards important callers to a user specified phone
number. When an important customer calls, OmniConnect dials other locations (such as a
cellular phone and an alternative work phone), and connects the caller even when the
OmniConnect user is away from the office. OmniConnect also provides real-time caller ID
support, notifying users of the incoming calls phone number so important calls will not be
missed. In addition, call ringing is distinctive based upon user’s needs.
2.1.6. Dial-on-demand routing
OmniConnect/ISDN includes dial-on-demand routing. Dial-On-Demand ensures that the
OmniConnect will automatically initiates a connection when data traffic is sent from the LAN
to the Internet. This allows LAN users connected to the OmniConnect to dynamically initiate
calls to remote devices across ISDN BRI lines as the need emerges. OmniConnect also
terminates ISDN connections when it senses that there is no demand on the ISDN line from
local users.
2.1.7. Bandwidth allocation control and bandwidth allocation protocols
Bandwidth Allocation Control Protocol (BACP) and the Bandwidth Allocation Protocol
(BAP) define a set of rules that gracefully control dynamic bandwidth allocation by managing
the number of links in a point-to-point protocol (PPP) multi-link bundle. BACP consists of a
network control protocol that negotiates once per PPP multi-link bundle while BAP defines a
set of request and response messages to manage the links.
OmniConnect/ISDN software supports dynamic management of both B channels.
Implementation of BACP and BAP allows OmniConnect access devices to coordinate and
negotiate the actual allocation and de-allocation of the second channel. The parameters are set
using the configuration screen. BACP is only implemented on a BRI interface.
Note: Multi-link PPP has to be negotiated for BACP to be functional.
If a data call is bumped to accommodate a voice call, and BAP negotiation is enforced, the
user might experience a very short audio idle period before a B channel becomes available. In
some cases, the user might not be able to connect the voice call if the peer (the user at the
other end of the data call) declines to terminate the link with the OmniConnect.

OmniConnect / ISDN User’s Manual Page 5
Part number 613-10787-00
2.1.8. DHCP server
DHCP automates IP addressing and reduces the number of IP addresses a site might require.
The OmniConnect can function as a dynamic host configuration protocol (DHCP) server.
When a DHCP server is enabled and configured, it assigns and manages IP addresses from a
specified address pool to DHCP clients. The options supported by this server are sufficient for
255 TCP/IP clients. If more IP addresses or options are required, a higher-capacity DHCP
server (i.e., Windows NT) could be used.
2.1.9. Network address translation
OmniConnect supports port or Network Address Translation (NAT) allowing a designated
private IP network to communicate with the outside world. When configured, OmniConnect
translates source addresses from an IP private network to a single, global, unique IP address
before forwarding the packets to the outside world. OmniConnect’s implementation of NAT
supports a variety of multimedia applications, games and standard utilities such as telnet, FTP
and HTTP by carefully monitoring each applications use of IP addresses and port numbers. In
addition, the OmniConnect/ISDN allows unsolicited UDP and TCP requests from the Internet
to be routed directly to a single client based solely on port number. This allows applications
that require conversations or connections to be initiated from the Internet such as Diablo,
Microsoft NetMeeting and CuSeeMe to operate correctly. In addition, the
OmniConnect/ISDN allows users to place web servers or email servers on the local LAN, by
allowing holes in NAT. This allows users to access an internal web server that uses a globally
administered IP address from the Internet.
2.1.10.IP address assignment through IPCP
The access device can be assigned an IP address from the remote device using Internet
Protocol Control Protocol (IPCP) address negotiation. The implementation is based on
RFC1332. IPCP address negotiation is on by default in any profile configured for IP routing.
This feature does not support assigning addresses to remote devices.
2.1.11.Force dynamically negotiated IP addresses
When this feature is off, the negotiated IP address is assigned to the standard or the user-
defined address. It also tells the software to try any IP address configured for this port in
PPP’s IP address negotiation. When this feature is on and the internal profile does not contain
an address, the negotiated IP address is automatically assigned to the internal profile by the
system. If the Internal profile contains an address, it will be assigned to the user-defined
profile from which the call was initiated.
2.1.12.Data compression
The OmniConnect access device supports data compression using the compression algorithm
QIC-122 standard, Stac LZS. Data compression is a software configuration option that
optimizes the ISDN line bandwidth. Packets are compressed before being sent onto the ISDN
line. After they arrive at their destination, the packets are decompressed and sent on to the
remote LAN.
2.1.13.Flash firmware upgrade
The OmniConnect/ISDN remote access / access device, stores its firmware in FLASH read-
only memory (ROM). The FLASH ROM allows the OmniConnect/ISDN access device
firmware to be easily upgraded using the local serial console port. Firmware upgrades may be
downloaded from the OmniConnect web site at http://www.alliedtelesyn.com. All current
configuration parameters for the OmniConnect/ISDN are stored in non-volatile storage. The
configuration parameters can be stored or retrieved via both the serial console port and the
OmniConnect configuration manager.

OmniConnect / ISDN User’s Manual Page 6
Part number 613-10787-00
2.2. Security features
The OmniConnect/ISDN access device provides the following security features:
•PPP authentication support, including Password Authentication Protocol
(PAP) and Challenge Handshake Authentication Protocol (CHAP)
•Password security for local and remote telnet and configuration access
•TCP, UDP and IP filtering based on source and destination IP addresses,
source and destination ports TCP and UDP ports, and IP packet types.
•Network Address Translation and Port Address Translation. All local,
private IP addresses are translated to a single, globally unique IP address,
with a unique port number, thus hiding the local station’s addresses and port
numbers from external users. Unless specifically authorized, no externally
generated connection can create a connection with an internal client.
2.3. Supported RFCs
The OmniConnect/ISDN access device supports the following Request For Comments (RFC)
documents:
RFC 1058 - Routing Information Protocol (RIP)
RFC 1332 - PPP Internet Protocol Control Protocol (IPCP)
RFC 1334 - PPP Authentication Protocols
RFC 1541 - Dynamic Host Configuration Protocol (DHCP)

3.1. Definition of terms
The following terms used in this manual are used during the configuration process.
Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) - A digital
communication medium that operates over existing analog telephone lines provided by the
telephone company. ISDN BRI provides two 64 KBPS Bearer (B) channels for voice and data
and one 16 KBPS D channel for customer and call information. ISDN BRI is usually denoted
as 2B+D.
Service Profile Identifiers (SPIDs) – These are numbers assigned by the ISDN service
provider that identify the ISDN B channels. The SPID format is generally the ISDN telephone
number with several numbers added to it. Depending on the switch type supporting your
ISDN BRI line, your ISDN line might be assigned none, one, or two SPIDs. They are
assigned only in North America.
Directory numbers - The ISDN equivalent of standard telephone numbers. These are the
numbers the access device dials to connect to a remote access device or the numbers that
users dial to connect to a POTS or telephone line attached to the local access device. In order
to use the OmniConnect access device’s powerful call management features to the fullest
extent, it is recommended that multiple Directory Numbers or DNs are for the ISDN BRI line
are ordered along with the line. ISDN BRI lines are generally assigned two local directory
numbers, one for each B channel. However, most Bell Operating Companies and telecom
providers allow up to 8 or 16 Directory Numbers assigned to each line.
Access code - A number that must be dialed preceding the telephone number to dial outside
of a specific telephone system, such as a Centrex system. Examples of this are the ‘9’ that
precedes the telephone number.
Internet Protocol (IP) address - A network address that uniquely identifies a device on an IP
network. This type of address consists of 4 bytes, represented as decimal values, separated by
periods, e.g., 192.168.2.143.
Media Access Control (MAC) address - This 48-bit address is assigned by the device
manufacturer to define the Ethernet address of the device. All OmniConnect access devices
have MAC addresses of the form 00-10-98-xx-xx-xx. Each byte is represented as a
conventional two digit hexadecimal number.
Point-to-Point Protocol (PPP) - A serial protocol defined in RFC 1661 that is used to
provide point-to-point connectivity over serial links.

Part number 613-10787-00
Password Authentication Protocol (PAP) - A form of PPP authentication that requires an
exchange of user names and clear-text passwords between two devices. PAP passwords are
sent unencrypted.
Challenge Handshake Authentication Protocol (CHAP) - A form of PPP authentication
that requires an exchange of user names and secrets (encrypted passwords) between two
devices. This security feature is supported on lines using PPP encapsulation. CHAP
passwords are called secrets because they are sent encrypted.
3.2. Helpful information
This section provides information located in this user’s manual that is useful in configuring an
OmniConnect/ISDN remote access / access device.
3.2.1. Ordering an ISDN BRI line
If you have not yet ordered an ISDN BRI line, refer to the worksheet and instructions
provided at the end of this chapter, in the section entitled ISDN Provisioning Worksheet and
Information.
3.2.2. ISDN ordering codes (IOCs) user guide
ISDN is a complex service with many network options. ISDN service is usually ordered using
ISDN ordering codes (IOCs), which simplify the connection and installation of ISDN. If your
local telephone company supports IOCs, see the sub-section entitled ISDN Provisioning with
IOCs. If your local telephone company does not support IOCs, see the sub-section entitled
ISDN Provisioning without IOCs. To help in this process, OmniConnect products support the
most common central office switches in a variety of configurations. IOC Codes EZ-ISDN 1
(Capability U) and Capability S1 are recommended for use in North America with the
OmniConnect/ISDN access device products.
3.2.3. Cabling
The OmniConnect/ISDN access devices use a DB-9 female connector. See the section entitled
Cabling at the end of this chapter for a description on the cable connections
3.2.4. Stacking
You must remove the interlock cap (endstop) at each corner of the unit from every
OmniConnect except the one, which will be on top. From the side of the unit, insert the tip of
a small straight-slot screwdriver into the opening of the interlock cap. Press down on the
screwdriver to pry the cap off.
Install the square rubber bumpers on the base unit.
Note: The LanEdge products will not interlock (stack) properly if the square rubber
bumpers are installed on the interlocking (upper) unit; install these bumpers only on
the base unit.
To interlock the units into a stack, place the base unit on the desktop, then place the next unit
over the base (or stack) and press down on each corner to snap the units together. Repeat until
all units are in the assemblage.

3.3. Safety recommendations & maintenance
These guidelines must be followed to ensure safety and proper maintenance.
•Do not attempt to remove the top or bottom covers, as you may be exposed
to a shock hazard. Only qualified service personnel should attempt to
remove the covers.
•Do not place items on top of the OmniConnect/ISDN chassis as these items
may fall into the vents or cover them and prevent proper cooling of the
electronic devices.
•Do not expose the OmniConnect chassis to rain or excessive moisture to
avoid the risk of shock or permanent damage to the set.
•Consult a service technician if, after following all instructions in this
manual, the OmniConnect still does not operate correctly.
•Keep the chassis area clear and dust-free during and after installation.
•Do not use alcohol or any ammonia-based liquid to clean the OmniConnect
chassis. If necessary, wipe with a dry, lint free cloth.
hWARNINGS!
Hazardous voltages are present in the BRI ISDN cable. If you detach the cable, detach
the end away from the OmniConnect first to avoid electrical shock. Hazardous voltages
are also present on the Printed Circuit Board (PCB) in the area of the BRI ISDN RJ-45
connector.
The installation and configuration of the system should not occur during periods of
lightning activity.
Users should not tamper with the ISDN connection.
Ports labeled “10Base-T” and “Console” are safety extra-low voltage (SELV) circuits.
SELV circuits should only be connected to SELV circuits. Do not connect the 10Base-T
connectors (RJ-45) to the BRI ISDN connection as this will result in permanent damage
to the OmniConnect access device.
Ultimate disposal of this product should be handled according to all relevant
international, federal, state, and local regulations.

3.5. ISDN provisioning information & worksheet
This section describes the process of ordering and provisioning an ISDN BRI line to operate
with the OmniConnect/ISDN. Both the ISDN BRI line configuration and the OmniConnect
configuration are dependent upon the ISDN switch that is used by the local telephone
company that is providing the ISDN service. Some local telephone companies allow the use
of ISDN Ordering Codes (IOCs) to simplify ISDN ordering. The ordering codes reflect a
standard set of commonly used configurations for ISDN BRI. If the local telephone company
does not support IOCs, detailed provisioning requirements must be provided. The following
subsections provide describe provisioning the ISDN line for use with the OmniConnect.

3.5.1. Data and voice applications over ISDN BRI
The OmniConnect/ISDN supports both data and voice applications. Voice applications can be
initiated via the analog telephone port on the OmniConnect access device. If voice capability
is not required, it is possible in some areas to provision the line for data only support. This
may be the preferred option since some ISDN service providers tariff data only lines less than
data and voice lines.
In addition to supporting both voice and data services, the OmniConnect supports Data Over
Voice (DOV) bearer services. In some service areas, provisioning the ISDN line for DOV
bearer service is more inexpensive than data bearer services. DOV is chosen during the ISDN
configuration process.
The use of the analog line requires the use of Additional Call Offering (ACO) services and a
BRI configured for both voice and data applications. ACO allows the user to receive voice
calls when both B channels are being used for data applications. However, regardless of the
type of ISDN service, a voice call cannot be received when there are data calls that have been
made to two different sites. AT&T Custom services (as opposed to NI-1) have an additional
limitation; a voice call cannot be received when both B channels are being used for data.
Outgoing calls are not affected by this limitation since the OmniConnect controls them.
In North America, if the local ISDN connection is supported by an AT&T 5ESS switch, it is
recommended that IOC U/EZ-ISDN 1, IOC V/EZ-ISDN 1A with support for simultaneous
voice and data or IOC S/S1 (if not using an AT&T switch) is ordered for the OmniConnect. In
order to take complete advantage of the advanced call management features of the
OmniConnect access device, it is required that multiple directory numbers (DN’s) or phone
numbers be ordered along with the ISDN line. OmniConnect accommodates multiple phone

OmniConnect / ISDN User’s Manual Page 14
Part number 613-10787-00
numbers attached to a single phone (each ringing the same phone). This helps the user
respond to incoming calls differently based on the number dialed.
3.5.2. ISDN switch types
The OmniConnect/ISDN supports the switch types described in this section. In North
America, telephone companies primarily provide BRI service with AT&T or Northern
Telecom switches
3.5.2.1. National ISDN-1
National ISDN-1 (NI-1) BRI switches comply with established National (United States) ISDN
standards. This type of line is supported by AT&T, Northern Telecom and other
manufacturers’ switches. If possible, this type of BRI line should be ordered from the
telephone company service provider since National ISDN-1 switches are guaranteed to offer
Additional Call Offering (ACO). ACO allows the ISDN user to receive an incoming call
when both B channels are in use.
3.5.2.2. AT&T 5ESS Custom
AT&T 5ESS switches can operate in custom mode, in addition to NI-1 mode (explained
above). Custom mode allows the switch to be configured to operate in either a point-to-point
or a multipoint configuration. Point-to-point configurations support one piece of terminal
equipment on the BRI line and do not require Service Profile Identifiers (SPIDs).
Note: For information on SPIDs, please see the section entitled SPIDs.
It is not possible to support two voice channels simultaneously on a Custom Point-to-Point
link. Therefore, Point-to-Point service only requires the provisioning of one telephone number
for both B channels. Multipoint configurations support multiple pieces of terminal equipment
on the same BRI line and requires SPIDs.
3.5.2.3. Northern Telecom DMS-100 Custom
Northern Telecom DMS-100 switches support a custom mode used with older terminal
equipment in addition to NI-1.
3.5.2.4. EURO-ISDN ISDN BRI switch type
The EURO-ISDN switch type, also known as NET-3, is used in Europe and parts of Asia,
including the United Kingdom, France, Germany, Singapore, and Taiwan.
Note: International ISDN BRI lines are not assigned SPIDs; they are typically assigned a
single Directory Number.
There are two basic NET-3 (EuroISDN) implementation variants, termed NET-3 Asia and
NET-3 Europe. In European variations, the Called Party information is transmitted only in the
Q.931 called party information element, whereas in Asian variants, it is permitted (and
sometimes required) to be transmitted in an optional keypad information element.
3.5.2.5. 1TR6 ISDN BRI switch type
The 1TR6 switch type is used in Germany. The 1TR6 lines can be configured for multiple
subscriber numbers, usually referred to as "extended addressing" in Germany. The line is
usually assigned a group of eight sequential directory numbers that can be used for the
