Page 13 The SRG is implemented on a BCM 50 platform and is connected to a CS 1000 at the main ofﬁce through Virtual Trunks over a reliable IP WAN access facility. This conﬁguration allows the call processing for the IP Phones at the SRG site to be centralized at the main ofﬁce.

Page 20 In the event that the IP Phones at the branch ofﬁce lose the connection to the main ofﬁce CS 1000 call server for any reason (WAN failure, main ofﬁce call server failure, main ofﬁce Signaling Server failure), the SRG 50 reverts to Local Mode automatically.

This allows the main ofﬁce to identify attached clients and the local PSTN as branch ofﬁce entities, enabling proper operation of dial plans and E911 access.

Page 46: Zone-Based Digit Manipulation
For a given branch ofﬁce, there may be more than one zone deﬁned at the main ofﬁce. Therefore, different SRG users may receive different routing treatments. Main Ofﬁce Conﬁguration Guide for SRG 50 Copyright © 2005-2007, Nortel Networks Nortel Communication Server 1000 NN43001-307 02.02 Standard Release 5.0 3 December 2007...

The combination of zone-based digit manipulation and CS 1000 routing capabilities can be used to achieve many other routing outcomes for SRG user calls. Calling Line ID composition Digital manipulation is commonly used for digit insertion and deletion. It is also used for call type conversion before out-pulsing the digits to the Virtual Trunk.

Page 51 If DialingCode1, DialingCode2, or DialingCode3 are already present in the dialed digits, then they will not be re-inserted. Nortel recommends that the ZDP attribute for each branch ofﬁce zone be set to a unique non-dialable number within the dialing plan (for example 1019 or 999).

Page 95: Bandwidth Management
• "Network using Coordinated Dialing Plan" (page 154) Introduction CS 1000 supports Bandwidth Management on a network-wide basis so that voice quality can be managed between multiple Call Servers. Bandwidth management allows for codec selection and bandwidth limitations to be placed on calls, depending on whether the calls are intrazone or interzone.
Page 96 Codec conﬁguration is performed for each node and is independent of the signaling gateway that is used on the node. The payload size on the CS 1000 must be set to 30 msec in order to work with the SRG.
Page 97 Bandwidth management enables administrators to deﬁne codec preferences for IP Phone to IP Phone calls controlled by the same CS 1000 system in the same zone. These calls are known as intrazone calls. This is different than the codec preferences for calls between an IP Phone on the CS 1000 system to a Virtual Trunk (potentially an IP Phone on another CS 1000 system) or calls to IP Phones in another zone.
Page 98 Each codec list contains more than one payload size for a given codec type (it depends on the codec conﬁguration). Payload size must be set to 30 msec for proper functionality between the CS 1000 and the SRG. • Each codec list is sorted by order of preference (the ﬁrst codec in the near end’s list is the near end’s most preferred codec, the ﬁrst codec in...
Page 99 Master/Slave information, is needed. Since any change to the Master/Slave algorithm implies a change to the H.323 standard, the new codec algorithm is used for Virtual Trunk calls between Nortel equipment. SIP Offer/Answer model The SIP codec negotiation is based on the Offer/Answer model with Session Description Protocol (SDP).

Description • • • Adaptive Network Bandwidth Management CS 1000 Release 4.5 supports the Adaptive Network Bandwidth Management feature. Description The Adaptive Network Bandwidth Management feature enhances the performance of Voice over Internet Protocol (VoIP) networks based on real-time interaction. It provides the means to automatically adjust bandwidth limits and take corrective action in response to Quality of Service (QoS) feedback.
Page 111 Call Servers age out the old Call Server information and therefore, provide only up to date bandwidth information. This feature operates between all IP Peer CS 1000 systems, including the Media Gateway 1000B and Survivable Remote Gateway 50.

Page 159: Alternative Call Routing For Network Bandwidth Management
Description Alternative Call Routing for Network Bandwidth Management (NBWM) is available for CS 1000 Release 4.5 and CS 1000 Release 5.0 . Alternative Call Routing for Network Bandwidth Management (NBWM) allows a station-to-station call (that is, a call that does not use a trunk) between a branch ofﬁce and main ofﬁce to overﬂow to traditional routes.
Page 160 WAN bandwidth against the incremental cost of overﬂowed calls. Nortel recommends that this feature be used with DID (Direct Inward Dial) numbers. This allows calls that are rerouted over the PSTN to ring the intended telephone directly.
Page 161 The ALTPreﬁx applies to the zone in which the call originates. There is one ALTPreﬁx for each zone that requires alternate routing. All Call Servers must be able to translate the ALTPreﬁxes for all zones that require Alternative Call Routing for NBWM.
Page 162 With the ALTPreﬁx digits inserted, the resulting number must be one that CDP or VNR software can process as a steering code. Main Ofﬁce Conﬁguration Guide for SRG 50 Copyright © 2005-2007, Nortel Networks Nortel Communication Server 1000 NN43001-307 02.02 Standard...
