New in this release

This document is a global document. Contact your system supplier or your Nortel representative to verify that the hardware and software described are supported in your area.

This document describes the Branch Ofﬁce feature and contains information on planning, installation, conﬁguration, and maintenance. Information in this document complements information found in documents in the Communication Server 1000 documentation suite, as listed in Related information.

This NTP contains information about systems, components, and features that are compatible with Nortel Communication Server 1000 Release 5.0 software. For more information on legacy products and releases, click the

MG 1000B hardware platform

The MG 1000B system has been enhanced for CS 1000 Release 5.0 Branch Ofﬁce. The CP-PM Call Server and MGC replace the Small System Controller (SSC) used in the Release 4.0 and 4.5 MG 1000B.

Release 5.0 20 June 2007

18 New in this release

Media Card MC32S

For CS 1000 Release 5.0, the new Media Card 32S (MC32S) fully replaces the functionality of the current VGMV pack NTVQ01BB. You can use the new pack in both large and small systems, and anywhere you can use the current NTVQ01BB pack. The MC32S also adds SRTP security. For an MGC-based MG 1000B, the sets are conﬁgured in four-ﬁeld format.

As there are new conference capabilities on the MGC, the Group Call feature available in CS 1000 Release 5.0 on the CS 1000B is enhanced. The number of group members increases from 6 to 20.

Main and Branch Ofﬁce running different releases

If the main ofﬁce Call Server is running CS 1000 Release 5.0, the Branch Ofﬁce can run on CS 1000 Release 5.0, CS 1000 Release 4.5, or CS 1000 Release 4.0.

Customers will no longer be permitted to order a Branch Ofﬁce running on Succession 3.0.

Main Ofﬁce and Branch Ofﬁce Migration

All Main Ofﬁce call servers in CS 1000 Release 5.0 are large system based. A CS 1000 Small System Main Ofﬁce is no longer supported. Since all CS 1000 Release 5.0 Small System Controller (SSC) based Main Ofﬁces have been migrated to Call Processor Pentium Mobile (CP-PM) Call Servers, the Main Ofﬁce TN (MOTN) Type in a Branch Ofﬁce will always be set to the large system MOTN Type.

In a system where the Main Ofﬁce has been migrated from a SSC to CP-PM call server, the LD 20 PRT on the branch will not correctly display the MOTN using the small system TN format until the branch has been migrated or upgraded to CS 1000 Release 5.0. In the case where the branch is SSC based, the LD 20 PRT will remain incorrect until the Branch Ofﬁce Call Server has been migrated to a CP-PM call server. In the case where the branch is already linked to a Large System Format Call Server, the LD 20 PRT report on the branch will remain incorrect until the branch has been upgraded to CS 1000 Release 5.0.

What is Branch Ofﬁce?

The Branch Ofﬁce feature extends CS 1000 features from a main ofﬁce to one or more remote ofﬁces.

The Branch Ofﬁce feature is implemented on a Media Gateway 1000B (MG 1000B) platform. The MG 1000B platform includes an MG 1000B Core connected to an IP PBX at the main ofﬁce over a LAN or a WAN. This conﬁguration enables a secondary location to centralize the call processing of its IP-based communication network. The Call Server at the main ofﬁce provides the call processing for the IP Phones in both the main ofﬁce and Branch Ofﬁce locations. The MG 1000B Core provides call processing functionality to local digital telephones and analog devices. The MG 1000B Core also provides digital and analog trunk access to the local Public Switched Telephone Network (PSTN).

The MG 1000B platform connects to the main ofﬁce over Virtual Trunks on a LAN/WAN. The main ofﬁce transmits and controls IP Phone calls and IP network connections. If the main ofﬁce fails to function, or if there is a network outage, the Media Gateway Controller (MGC) card in the MG 1000B Core provides service to the telephones located at the Branch Ofﬁce location. This enables the IP Phones to survive the outage between the Branch Ofﬁce and the main ofﬁce.

Currently, MG 1000B Branch Ofﬁce is small system based; which is still supported in CS 1000 Release 5.0. In addition, changes are made to allow large system based branch ofﬁces. Branch Ofﬁce conﬁgurations supported in CS 1000 Release 5.0, and are not changed with the CP PM (Call Processor Pentium Mobile). Additionally, the CP PM adds the ability

for large systems to be supported as a Branch Ofﬁce. A mixture of pre CS 1000 Release 5.0 branches are supported with CS 1000 Release 5.0 branches as long as the main ofﬁce is running the latest software.

The Branch Ofﬁce feature does not change with the addition of large system based branches. The Branch Ofﬁce feature is ported to a large system. Both small and large systems are supported as either main or branch ofﬁces with only one restriction; the main must be running the highest release of software.

Support is available for CS 1000 Release 5.0 Branch Ofﬁce features, as long as the main ofﬁce is running the highest release of software. For example, Branch ofﬁces can be either the SSC based MG 1000B (CS 1000 Release 4.5), or the new MGC based MG 1000B (CS 1000 Release 5.0).

With CS 1000 Release 5.0 and the introduction of the new hardware platforms, the following conﬁgurations are supported:

•

Main Ofﬁce: MGCbased system. Branch Ofﬁce: MGC based MG 1000B.

•

Main Ofﬁce: MGC based system. Branch Ofﬁce: MGC based MG 1000B (large system software stream).

•

Main Ofﬁce: Large system (1000M or 1000E). Branch Ofﬁce: MGC based MG 1000B.

•

Main Ofﬁce: Large system (1000M or 1000E). Branch Ofﬁce: MGC based MG 1000B (large system software stream).

For small Branch Ofﬁce conﬁgurations, the Survivable Remote Gateway feature can provide the same functionality and beneﬁts as the Branch Ofﬁce feature.

You can implement the Branch Ofﬁce feature as a new hardware conﬁguration. It can also be created by converting an existing Small System to an MG 1000B platform (see "Converting a Small System to a Branch

Ofﬁce" (page 201)). The functionality is the same in both conﬁgurations.

The main ofﬁce can be any one of the CS 1000 systems (see ""Main ofﬁce

hardware description" (page 28)" More than one Branch Ofﬁce location

can be associated with a single main ofﬁce. In addition, one Branch Ofﬁce location can be associated with more than one main ofﬁce.

A Branch Ofﬁce is designed to work with a main ofﬁce only if the two ofﬁces use a common dialing plan. Any other conﬁguration is not guaranteed to work properly.

Main Ofﬁce and Branch Ofﬁce Migration

In a system where the Main Ofﬁce has been migrated from a SSC to CP-PM call server, the LD 20 PRT on the branch will not correctly display the MOTN using the small system TN format until the branch has been migrated or upgraded. In the case where the branch is SSC based, the LD20 PRT will remain incorrect until the Branch Ofﬁce Call Server has been migrated to a CP-PM call server. In the case where the branch is already a large system (CP-PII or CP-PIV), then the LD 20 PRT on the branch will remain incorrect until the branch has been upgraded to CS 1000 Release 5.0.

MG 1000B (MGC) compared to the MG 1000B (SSC)

The MG 1000B with MGC has a number of differences in hardware capability when compared with Release 4.5 gateways.

The MGC has six Ethernet interfaces for connecting to external networking equipment. Three are reserved for ELAN connections and three are reserved for TLAN1 connections. The six external Ethernet interfaces on the MGC are set to Auto Negotiate mode by default. You can change the settings for ports 1E, 2T, E and T to 100 Mbps full duplex by using the

mgcsetup command. With a properly designed data network, the multiple ELAN and TLAN interfaces can be used to implement a dual homed conﬁguration for the MG 1000B with MGC.

Four of these interfaces are accessed by using RJ45 connectors on the faceplate. Two are reserved for ELAN and two are reserved for TLAN.

Two additional Ethernet connections are available if an Option 11C cabinet is used. One is reserved for ELAN and one is reserved for TLAN.

For the Option 11C cabinets, to break out the two new 100BaseT Ethernet connections, you need a new backplane adapter. This adapter replaces the MDF-to-AUI cable used for the 10BaseT Ethernet connection on the existing system.

One use for the additional LAN connections is to allow for network redundancy, also known as dual-homing on the Release 4.5 MG 1000B. The MGC Ethernet interface failover is accomplished with the embedded Ethernet switch. The Ethernet interface failover feature requires no special network conﬁguration to function. The end customer decides if two separate Layer 2 switches are used to implement the feature to minimize the service outage. For more information see the Communication Server 1000E: Installation and Conﬁguration (NN43041-310) NTP.

Also, you can use the broadcast and multi cast rate limiting features of the embedded Ethernet switch on the MGC to reduce the susceptibility of the Call Server to broadcast storms and similar network issues, if you directly cable the Call Server to the MGC.

In addition, certain debug features use the LAN connections (for example, port mirroring.)

The MGC has two conference loops with thirty units each. The maximum number of participants in a conference is thirty. On the MG 1000B, the maximum number of conference loops was four with sixteen units in each loop. The maximum number of participants in a conference was six.

The MGC has a four-character alphanumeric LED display on the faceplate. the boot and application software use the display to show diagnostic information to the technician.

The MGC has a clock reference input/output to support the requirements of the Digital Enhanced Cordless Telecommunications (DECT) standard. The DECT product requires a tight clock tolerance between cabinets with interconnected radio equipment of ±5ppm. To accommodate the tight clock

26 Overview

tolerance, the MGC is equipped with a clock reference input/output. The clock reference input and output connections and cable detect are provided through a 15-pin DSUB connector.

MGC Serial Ports

Each MGC installed in a CS 1000B provides the opportunity for 3 remote SDIs. The maximum number of TTYs does not change. Therefore, after you conﬁgure the maximum TTYs , no additional TTYs are supported.

The MGC has three serial ports SDI0, SDI1, and SDI2. You can use serial ports for local debugging; or, you can conﬁgure the ports

in the MG 1000B Call Server as system terminals in LD 17. During the initial conﬁguration of the MGC, you must connect to either

SDI0 or SDI1 to access the installation menu. Only SDI0 has full modem support, as SDI1 and SDI2 have no hardware ﬂow control (limitation of the three-port cable used).

SDI2 is not available during the MGC bootup; therefore, you cannot use it to access the installation menus.

Unlike the NTDK20xx SSC card, all SDI ports on the MGC are conﬁgured by using shipped software. No DIP switches are on the MGC for conﬁguring the baud rate of SDI0.

Single CPU Implications

Single CPU installations do not require dynamic binding of TTY ports to the active CPU because only one CPU exists. Therefore, single-CPU installations can use the Call Server TTY ports or the MGC remote TTY ports.

Dual CPU Implications

MG 1000B uses a terminal server to ensure that serial ports are always bound to the active CPU. The remote SDIs on the MGC provide similar functionality. Each MGC provides three SDI ports that you can provision in the softswitch as TTYs.

Remote TTY provisioning is enhanced over the terminal server model. SDI port provisioning is performed on the softswitch and does not require local provisioning at the IPMG.

Terminal Server Support

The remote SDI feature on the MGC eliminates the need for a terminal server.

MGC serial port default conﬁguration

The default settings for the serial ports are

•

Baud rate = 9600

•

Number of data bits = 8

•

Number of stop bits = 1

•

Parity = none

•

Flow control = none

MGC serial ports conﬁguration change in Overly 17

If you conﬁgure the serial ports on an MG 1000B with MGC as SL1 terminals on the Call Server, then the baud rate, number of data bits, number of stop bits, parity, and ﬂow control are conﬁgured in LD 17.

Any values conﬁgured in LD 17 are downloaded to the MGC and override the default values. The downloaded values are stored on the MGC and persist over restarts and power outages. When the serial port baud rate is changed, a system message indicates the change.

Support of CEMux requires CS 1000 Release 5.0 Softswitch software and a Media Gateway Controller Card (MGC). It is supported by all MG 1000B systems.

Features supported by Option 11C SIPE related to CEMux are supported in MG 1000B, which includes support for nB+D by having single D-Channel support trunk packs in separate MG1000Bs.

The TMDI D-Channel ISM used on small systems IS NOT included for the CS 1000B. D-Channels conﬁgured or removed for TMDI cards increment the existing large system software based DCH ISM. The maximum number of D-Channels, which is 255, supported with CS 1000B in CS 1000 Release

5.0, matches that of the CS 1000M large systems.

For BRI, you must provision the MISP and the SILC/UILC in the same IPMG. This is the only supported conﬁguration.

Clock References

With CEMux support, you can conﬁgure digital trunks and clock controller conﬁguration in the IPMG. Each IPMG that contains a digital trunk card requires a clock controller on that shelf. You cannot use Clock references across IPMGs, and you can conﬁgure only one clock controller per shelf..

The diagrams throughout this document show a CS 1000E main ofﬁce. All of the systems appearing in the list perform identical main ofﬁce functions as far as the Branch Ofﬁce feature is concerned.

MG 1000B platform hardware description

The MG 1000B system has been enhanced for CS 1000 Release 5.0 Branch Ofﬁce. The CP-PM Call Server and MGC replace the SSC (Motorola) used in the Release 4.0/4.5 MG 1000B. The Voice Gateway Media Card is still supported however, the DSPs are also available on the MGC.

Two new DSP Daughterboards are included in the CS 1000 portfolio of products. The daughterboards are available in two different sizes, a 32-port daughterboard and a 96-port daughterboard. These daughterboards are located on the Media Gateway Controller (MGC) card to provide DSP resources for connecting IP and TDM devices. These daughterboards eliminate the need to instal the Voice Gateway Media Cards within the CS 1000E Media Gateways (MG 1000B) chassis, to save slots and reduce cost over the current Voice Gateway Media Card solution. The addition of the DSP Daughterboards into a MG 1000B system does not limit the use of Voice Gateway Media Cards (either Pentium or Strong-Arm versions), either for DSP-only functionality or for the full IP Line application within the same system. The MGC is used only in the Media Gateway chassis or Option 11C-style cabinets. Froma functional perspective, the DSP Daughterboards behave in a similar manner as the current Voice Gateway (VGW) application on the Voice Gateway Media Card.

Support exists for four conﬁgurations:

•

a system with no DSP DBs or Voice Gateway Media Card (A pure TDM system, single media gateway).

•

a system with only Voice Gateway Media Cards

• a system with only DSP DBs — a 32-port daughterboard in daughterboard position 1 — a 32-port daughterboard in daughterboard position 2 — A 32-port daughterboard in daughterboard position 1 and a 32-port

daughterboard in daughterboard position 2 — a 96-port daughterboard in daughterboard position 1 — a 96-port daughterboard in daughterboard position 1 and a 32-port

daughterboard in daughterboard position 2

•

a system with DSP DBs (all of the position combinations described in c) and Voice Gateway Media Cards.

The basic hardware of an MG 1000B platform includes the MG 1000B Core and the Signaling Server.

Figure 2 CS 1000 Release 5.0 MG 1000B System

CS 1000 Release 5.0 continues to support the existing Branch Ofﬁce conﬁguration that uses the SSC processor, but Nortel no longer offers sales of the SSC based Branch Ofﬁce.

CS 1000 Release 5.0 provides various hardware versions of the Signaling Server, the existing ISP1100 signaling servers, or the new CP-PM Signaling Server.

With CS 1000 Release 5.0 Branch Ofﬁce, the hardware conﬁguration includes a CP-PM call processor card with the MGC, as well as a CP-PM Signalling Server. If the CP-PM Signalling Server conﬁguration cannot be used, the option exists to use the Signaling Server on COTS.

The MG 1000B Core and MG 1000B Expander can connect to either a LAN or a WAN.

An MG 1000B platform can be a new hardware conﬁguration. It can also be a Small System platform converted to an MG 1000B platform. In the latter case, the cabinet or chassis performs the same functionality as the
