Product description
The Z-Edge 64 is a compact integrated access device (IAD) that provides
Internet Protocol (IP) routing features as well as traditional voice services
over a single Digital Subscriber Line (DSL) WAN connection. The Z-Edge 64
BH2A offers Integrated Services Digital Network Basic Rate Interface (ISDN
BRI) voice transport. The Z-Edge 64 H2A supports Plain Old Telephone
Service (POTS).
Figure 1: The Z-Edge 64
In a traditional Voice over DSL (VoDSL) architecture, the Z-Edge 64 can
operate with a Digital Loop Carrier (DLC), like the Zhone Multi-Access Loop
Concentrator (MALC), or a voice gateway, such as a Zhone Sechtor 100A.
Figure 2 shows an example application for the Z-Edge 64.

Features and capabilities
14 Z-Edge 64 Configuration Guide
Figure 2: Typical Z-Edge 64 network application
Features
The Z-Edge 64 has the following features:
•Toll-quality voice support with custom calling features
•Internet Protocol (IP) routing
•Network Address Translation (NAT) capabilities
•Dynamic Host Configuration Protocol (DHCP) server/client functionality
•Simple Network Management Protocol (SNMP) manageability
Protocols and technologies
The Z-Edge 64 supports the following networking protocols and technologies.
You should have an understanding of these concepts before operating the
Z-Edge 64:
ATM
Asynchronous Transfer Mode (ATM) is a cell-based, high-speed networking
technology. The ATM cell has a fixed length of 53 bytes. The cell is broken
into two parts, the header and the payload. The header (5 bytes) contains the

Internet

PSTN
voice lines
LAN
connection

Protocols and technologies
Z-Edge 64 Configuration Guide 15
addressing information, and the payload (48 bytes) carries the voice or data
message. Since each ATM cell has its own addressing mechanism, the cells
can be sent asynchronously, or in any order.
ATM uses virtual channels (VCs) and virtual paths (VPs) to route cells in an
ATM network. A VC, identified by a virtual channel identifier (VCI) is a
connection between two communicating ATM entities. A VC consists of a
concatenation of one or more ATM links. A VC provides a certain quality of
service, which is defined in the ATM Traffic Descriptor. A VP, identified by a
virtual path identifier (VPI), is a group of VCs between two ATM endpoints.
A physical link can support many VPs. Similarly, a VP can contain many
VCs.
DSL
Digital Subscriber Line (DSL) technologies provide access to high-bandwidth
networks over a unshielded twisted pair (UTP) of copper wires. By using
frequencies above the telephone bandwidth (300Hz to 3,200Hz), DSL can
encode more data to achieve higher data rates than would otherwise be
possible in the restricted frequency range of a POTS network. The DSL
family includes several variations.
Symmetric Digital Subscriber Line (SDSL) provides data-only symmetric
transfer rates of up to 2.32Mbps over a single pair of copper wires. SDSL uses
the same 2B + 1Q signaling as ISDN. SDSL service requires that the customer
is no further than 10,000 feet from the central office. SDSL is defined in ITU
G.991.1.
Global Symmetric High-bit-rate Digital Subscriber Line (G.SHDSL) is
designed to operate with both HDSL and SDSL networks. G.SHDSL extends
the reach and transfer rates of DSL services. G.SHDSL supports adaptive data
transfer rates of 192Kbps to 2.3Mbps with a reach of over 20,000 feet. The
G.SHDSL specification (ITU standard G.991.2) allows for transmission over
single-pair and two-pair copper wires.
NAT
Network Address Translation (NAT) is an Internet standard that enables a
local area network (LAN) to use one set of IP addresses for internal traffic and
a second set of addresses for external traffic. Hosts in a private network can
transparently access an external network and enable access to selective local
hosts from the outside.
A NAT device connecting the public Internet and the network it serves
rewrites IP addresses and port numbers in IP headers. The packets appear to
be coming from a single public IP address of the NAT device, instead of the
actual source or destination.
NAT serves two main purposes: It provides a type of firewall by hiding
internal IP addresses, and it enables a company to define more internal IP

Features and capabilities
16 Z-Edge 64 Configuration Guide
addresses. Since the addresses are used internally only, there is no possibility
of conflict with IP addresses used by other companies and organizations.
DHCP
The Dynamic Host Control Protocol (DHCP) provides a mechanism through
which client computers using TCP/IP can obtain configuration parameters
(such as the default router and the Domain Name System [DNS] server,
subnet mask, gateway address, and lease time) from a centrally located DHCP
server. DHCP dynamic reconfiguration requires a DHCP server, a forwarding
agent in each router, and DHCP capability in each client TCP/IP stack. The
most important configuration parameter carried by DHCP is the IP address.
Dynamic addressing allows a device to have a different IP address every time
it connects to the network, and in some systems, the device IP address can
change while it is still connected to the network. DHCP also supports a mix of
static and dynamic IP addresses.
Figure 3: Z-Edge 64 as DHCP client
A DHCP client is an Internet host using DHCP to obtain configuration
parameters such as a network address. A DHCP server is an Internet host that
returns configuration parameters to DHCP clients. As a DHCP client, the
Z-Edge 64 receives its IP address and configuration parameters from a DHCP
server, such as the BAN.
RIP
Routing Information Protocol (RIP) is widely used for routing traffic on the
Internet and is an interior gateway protocol (IGP), which means that it
performs routing within a single autonomous system. RIP is based on
Internet
BAN
Z-Edge 64

Protocols and technologies
Z-Edge 64 Configuration Guide 17
distance-vector algorithms that measure the shortest path between two points
on a network, based on the addresses of the originating and destination
devices. The shortest path is determined by the number of hops between those
points. RIP routers maintain only the best route (the route with the lowest
metric value) to a destination. After updating its routing table, the router
immediately begins transmitting routing updates to inform other network
routers of the shortest route.
Routing Information Protocol version 2 (RIPv2) is the latest enhancement to
RIP. RIPv2 allows more information to be included in RIP packets and
provides an authentication mechanism.
SNMP
Z-Edge 64 users can manage their system with Simple Network Management
Protocol (SNMP) software. SNMP is based on network management stations
(managers) and network managed elements (agents). SNMP allows network
managers and network agents to communicate.
There are three types of SNMP transactions—a Get, a Set, or a Trap. The Get
and Set commands are sent from the manager to the agent to determine (Get)
or configure (Set) network variables and status. A Trap is an exception to this
SNMP transaction pattern, in that the Trap is an unsolicited event report sent
from the agent to the manager. When the SNMP manager receives the Trap
message, it can be stored in the Management Information Base (MIB) and
displayed on a terminal screen.
A MIB is a virtual database that identifies each manageable object by name,
syntax, accessibility, status, a text description, and a unique
manageable-Object Identification number (OID). MIBs come in three
varieties: Public, Experimental, and Private Enterprise.
Automatic rate adaption
Automatic baud rate detection (also known as rate adaption) allows receiving
devices to communicate with transmitting devices operating at different
speeds without the need to establish data rates in advance. By determining the
baud rate from the transmitting device, the receiving Z-Edge 64 automatically
trains to match the line rate of the incoming data.
Usually there is one central office (CO) device transmitting to many customer
premises equipment (CPE) units. When a CO device trains with a CPE unit,
the devices will settle on the lower of the two devices’line rates. It is optimal
to set the CPE line rate to 2320 kbps because it allows a wide range of rates
for CO and CPE devices to agree upon.
The training of line rates is faster on G.SHDSL than on SDSL. The G.SHDSL
rate adaption process occurs during the CO and CPE modems’handshake,
where the devices probe the G.SHDSL line to find the best possible line rate.
The SDSL autobaud process is slower because the CO and CPE modems use
an algorithm to step through a sequence of line rates, where the devices

Features and capabilities
18 Z-Edge 64 Configuration Guide
establish a connection at each line rate and then move to the next higher rate
until they reach the final rate, which is the lower of the line rates. Note that the
Z-Edge 64 does not currently support SDSL autobaud.
Physical interfaces
The Z-Edge 64 has following physical interfaces:
•WAN: One RJ11 port.
A standard RJ11 port connects unshielded twisted pair (UTP) copper wire
to DSL networks.
•LAN: One 10/100BaseT RJ45 port.
A RJ45 port carries both management and data traffic, and interconnects
with most Transfer Control Protocol/Internet Protocol (TCP/IP) hubs and
networks.
•Phone lines:
Z-Edge 64 BH2A: Four ISO 8877 ports support ISDN BRI.
or
Z-Edge 64 H2A: Four RJ11 ports support POTS.
•Serial: One DB9 port.
A single DB9 asynchronous serial port provides direct PC or virtual
terminal (such as VT100) access to the Z-Edge 64. The serial port allows
access to the CLI.

Managing the Z-Edge 64
Z-Edge 64 Configuration Guide 19
You can configure the Z-Edge 64 using any of the following methods:
•Simple Network Management Protocol (SNMP)
•Command Line Interface (CLI)
•Zhone Management System (ZMS)
SNMP
The Z-Edge 64 supports SNMP version 1 and version 2 for system
management. Network object variables are MIB-II compliant.
SNMP can be accessed over IP interfaces or the Ethernet interface. The
SNMP agent on the Z-Edge 64 uses port 161 of user datagram protocol (UDP)
for management traffic and UDP port 162 for error events and SNMP traps.
The MIBs for the Z-Edge 64 control the following:
•Data port configuration, status, and diagnostics
•General system management, field upgrades, and alarms
•Traps
CLI
The CLI is functionally similar to SNMP. The CLI commands are equivalent
to SNMP get and set commands and allow you to configure the unit. The
interface is accessible both using telnet and through a local serial port. You
can configure the same elements with the CLI as you can with SNMP.
ZMS
ZMS allows Z-Edge 64 users to navigate, monitor, and manage their Zhone
networks with a graphical user interface.
