553-3041-210 Standard 4.00 September 2007

The port-based VLANs used in the BayStack 470-24T switches operate in 
accordance with the IEEE 802.1Q tagging rules. VLAN ports are grouped 
into broadcast domains by assigning them to the same VLAN. Frames 
received in one VLAN can be forwarded only within that VLAN. For more 
information, see Communication Server 1000: System Redundancy 
(553-3001-307).

Connect the CAT5E RJ-45 LAN 2 port of Call Server 0 to a 100BaseT 
ELAN network interface on the local Baystack 470-24T switch.

Connect the CAT5E RJ-45 LAN 2 port of Call Server 1 to a 100BaseT port 
on the remote Baystack 470-24T switch.

Link the two Baystack 470-24T switches with two high-speed single-mode 
fiber uplinks (1 Gbps per link), using the built-in GBIC ports for dedicated 
uplink connectivity.

Assign three VLANs to the BayStack 470-24T ports.

Includes 2 ELAN network interfaces on the Call Servers, for 
example, for ELAN connections for Signaling Servers, 
MG 1000Es, Call Pilot, Symposium, OTM, Element Manager.

—

Four high-speed fiber uplinks (GBIC ports)

An MG 1000E performs functions under the direct control of the CS 1000E 
Core Call Server. The MG 1000E detects stimulus events from its interface
