Page 50 of 258 Bandwi dth Management 553-3001-207 Standard 2.00 January 20 06 Introduction CS 1000 supports Bandwidth Management on a network-wide basis so that voice quality can be managed between multiple Call Servers.
Bandwidth Managemen t Page 51 of 258 Main Office Configu ration for Survivable Remote Gateway 50 Configuration Guide By default, the G.711 co dec must be su ppo rted at both ends of a call. Codec configuration is performed for each node and is independent of the signaling gateway that is used on the node.

Page 56 of 258 Bandwi dth Management 553-3001-207 Standard 2.00 January 20 06 Interoperability be tween CS 1000 and SRG The SRG is designed to interoperate with CS 1 000 in a manner similar to MG 1000B but with a limitation with respect to codec select ion policy.
Bandwidth Managemen t Page 57 of 258 Main Office Configu ration for Survivable Remote Gateway 50 Configuration Guide Zones Bandwidth Management Zones are config ured for each endpoint on a Call Server. The Network Bandwidth Zone number determin es if a call is an intrazone call or an interzone call.

Emergency Services configuration Page 227 of 258 Main Office Configu ration for Survivable Remote Gateway 50 Configuration Guide With all sites using the same ESDN, a conflict occurs in the NRS. The conflict is resolved by using a unique pref ix for each site that the main office adds as it routes the call.
Page 228 of 258 Emer gency Services configuration 553-3001-207 Standard 2.00 January 20 06 The implications of rout ing calls to n odes wit hout direct ESA trunks are as follows: • At the node without the direct ESA trunks, the node cannot route the ESA call directly to the PSAP.
Emergency Services configuration Page 229 of 258 Main Office Configu ration for Survivable Remote Gateway 50 Configuration Guide ESA must be configured and tested on the main office Call Server and the SRG to differentiate between emergency calls or iginating from IP Phones at each location and calls or iginating on trunks.
