Avaya 555-245-600 사용자 설명서

For an S8700-series Server pair with direct/CSS/ATM PNC and duplicated control networks, 
control network A and control network B interfaces are administered as dedicated control 
networks and connected to duplicated IPSI circuit packs in the fiber-connected PNs. If a remote 
IP-PNC PN is introduced into the configuration, the S8700-series Server and IP-PNC PN may 
be administered for a single non-dedicated control network over the customer’s LAN. In this 
case, a third control network C may be administered on the S8700-series Server. The 
S8700-series Server automatically uses its own customer LAN interface port for Control 
network C.
Although this configuration allows the mixing of dedicated and non-dedicated control networks, 
it is discouraged. It is recommended that same control network to be configured across a 
combined IP-PNC and fiber-PNC system.

Any Enterprise Survivable Server (ESS) can also support a combined IP-PNC and fiber-PNC 
configuration in the event of failover to the ESS. Both an S8500 and an S87XX-series ESS can 
support single control and duplicated control networks for both the IP-PNC and fiber-PNC 
portions of the configuration. However, the ESS can support only those CSS-connected PNs 
that individually have an IPSI circuit pack and either a TN2302AP IP Media Processor or 
TN2602AP IP Media Resource 320 circuit pack. This limitation exists because the ESS 
provides only IP-PNC control and bearer service to PNs.

Processor Ethernet allows IP devices to register to an Avaya server without a need for 
TN799DP C-LAN boards. Prior to Communication Manager release 3.1, Processor Ethernet 
was permitted only when using S8300 or Shared Servers (e.g. Hosted IP Telephony). As of 
release 3.1, Processor Ethernet can also be used with the S8400 and S8500 Servers. 
Furthermore, as of release 3.1, S8500 can be used as an LSP (Local Survivable Processor).
