Security of
Your System:
Preventing
Toll Fraud
As a customer of a new telephone system, you should be aware that there is an
increasing problem of telephone toll fraud. Telephone toll fraud can occur in many forms,
despite the concerted efforts of telephone companies and telephone equipment
manufacturers to control it. Some individuals use electronic devices to prevent or falsify
records of these calls. Others charge calls to someone else’s number by illegally using
lost or stolen calling cards, billing innocent parties, clipping on to someone else’s line, or
breaking into someone else’s telephone equipment physically or electronically. In certain
instances, unauthorized individuals make connections to the telephone network through
the use of remote access features.
Common carriers are required by law to collect their tariff charges. While these charges
are fraudulent charges made by persons with criminal intent, applicable tariffs state that
the customer of record is responsible for payment of all long-distance or other network
charges. MCK Communications cannot be responsible for such charges and will not
make any allowance or give any credit for charges that result from unauthorized access.
To minimize the risk of unauthorized access to your MCK Communications,
PBXgateway, when possible, restrict the off-network capability of off-premises callers,
using calling restrictions, Facility Restriction Levels, and Disallowed List capabilities.
When possible, block out-of-hours calling through Time-of-Day Routing. Frequently
monitor system call detail reports for quicker detection of any unauthorized or abnormal
calling patterns.
Limit out-calling to persons on a need-to-have basis.
The MCK Communications PBXgateway, through proper administration, can help you
reduce the risk of unauthorized persons gaining access to the network. However,
telephone numbers and authorization codes can be compromised when overheard in a
public location, lost through theft of a wallet or purse containing access information, or
when treated carelessly (writing codes on a piece of paper and improperly discarding
them).
Additionally, hackers may use a computer to dial an access code and then publish the
information to other hackers. Substantial charges can accumulate quickly. It is your
responsibility to take appropriate steps to implement the features properly, to evaluate
and administer the various restriction levels, and to protect and carefully distribute
access codes.
Under applicable tariffs, you will be responsible for payment of toll charges. MCK
Communications cannot be responsible for such charges and will not make any
allowance or give any credit resulting from unauthorized access.

PBXgateway System Administrator’s Guide 10
FCC
Regulations
MCK Communications PBXgateway, complies with FCC Part 15, Subpart B, Class B.
If the MCK Communications PBXgateway causes harm to the telephone network, the
telephone company will notify you in advance that temporary discontinuance of service
may be required. If advance notice isn’t practical, the telephone company will notify
the customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or
procedures that could affect the operation of the equipment. If this happens, the
telephone company will provide advance notice in order for you to make the necessary
modifications in order to maintain uninterrupted service.

Product
Summary
The PBXgateway is a multi-user telephony device enabling remote teleworkers
seamless connectivity and full functionality of the corporate Private Branch Exchange
(PBX). The PBXgateway is referred as a “gateway ” because it is the central receiving
point for routing voice conversations from one or more locations to the PBX.
Teleworkers, usually working from an off-site location, can place a call through the
corporate PBX by simply dialing the number as if they were in the main office.
Single Users
Single remote users can connect their digital phones through the EXTender4000 for
IP:
Multiple-
Users
Remote offices with multiple users can be connected through one of the following
devices:
 EXTender6000, 8 & 12-user: You can use 3 EXTender 6000 8-user devices,
or 2 EXTender 6000 12-user devices.
The single-user devices are commonly referred to as a “Remote unit” and the multi-user
devices are referred to as “Branch Office units”.

PBXgateway System Administrator’s Guide 15
What is the EXTender4000 for IP?
The EXTender4000 provides remote voice access to a corporate PBX for a single remote user.
Remote users can connect to the PBXgateway via a 10/100BaseT Ethernet connection using IP packet
transmission. Remote users’ phones will connect into the remote module via an RJ-45 phone jack, and
their phone traffic will be placed in IP packets and sent out to the LAN via a 10/100BaseT Ethernet
connection to the PBXgateway.
Types of Network Connections
The PBXgateway is designed to connect over a wide variety of third party network devices using three
types of network connections:
 Synchronous-Serial connection (V.35, RS-530, RS-232)
 Asynchronous-Serial connection (RS-232)
 IP (10/100BaseT Ethernet)
Voice Transmission
At both the branch office and corporate sites, all voice and signaling information is placed into digital data
packets, which are then sent out over the data network. This data is transmitted digitally over the
connection as a series of “ones” and “zeroes”. The data packets are encapsulated within a MCK
Proprietary protocol called Remote Voice Protocol(RVP)
The most important consideration for packetizing voice is defining when each character begins.
Synchronous-vs Asynchronous Transmission
One way to do this is by providing a clock signal. At a precise time, the transmission starts. This is called
Synchronous (see page 18). In Asynchronous transmission, there is no clocking signal. The receiving
terminal knows what’s what because each character begins with a start bit and ends with a stop bit (see
page 19).
(VoIP)
The voice and signaling packets are sent using Internet Protocol (IP) over the packet-switched data
networks as opposed to using the traditional circuit-switched protocols. Voice packets get delivered to the
alternate device using the RVP. This protocol handles the timing and delivery of the packets. (See page
20 for more information)

Synchronous-Serial Connection
Synchronous
-Serial
Definition: A connection type utilizing the RVP protocol, encapsulated over HDLC, to
send voice packets over the network (using traditional network devices: TA,
CSU/DSU, FRAD) using a synchronous-serial bit stream via the WAN port of the
unit. A synchronous connection relies on a master clock (an oscillator generated
signal) to identify the starting point of each digital bit (ons & offs or “ones” and
“zeroes”) being sent. Voice packets are spaced by time.
Connection Type:
RVP_Direct
Advantages:
 Synchronous transmission of data requires fewer bits (and takes less time).
 Uses common network circuits.
 Circuit switched networks are generally more reliable for voice transmission.
Network types:
 T1/FracT1
 Switched 56/64K
 ISDN
 Frame Relay
 ATM
Connection:

PBXgateway System Administrator’s Guide 19
Asynchronous-Serial Connection
An Asynchronous-Serial Connection is a connection where voice packets are sent at irregular intervals.
Each voice packet is preceded with a Start Bit and followed by a Stop Bit. The timing of the transmission
is not determined by the timing of a previous character.
Figure 3: Asynchronous Transmission Data Bits
Advantages:
 Used in lower speed transmission
 Less expensive

Voice over IP (VoIP)
Voice over
IP
(VoIP)
Definition: A network connection allowing voice packets to be delivered to the
alternate site using the Internet Protocol (IP). In most IP circuits two types of
devices are utilized. A server (PBXgateway) is the main hub of information being
requested, and a client (the Remote unit) or user obtaining the information. The
Remote unit receives the voice packets from the user phone and transmits the
packets via the LAN and sends them over the WAN to the PBXgateway at the
corporate facility.
Connection Type:
RVP_IP
Advantages:
 Avoids toll charges charged by ordinary telephone services.
 IP connections are common and readily available.
 Makes use of existing network infrastructure.
 Avoids fixed costs associated with T1 & ISDN circuits.
