Each port can be independently software-configured as an IMA port or an ATM port. ¥ Structured service is digital cross-connect (DCS) type service where Nx64 Kbps and Nx56 Kbps circuits are mapped to unique ATM VCs; N = 1 to 24 (DS-1)/31 (E1) contiguous or non-contiguous DS-0 channels per DS-1/E1 port. Unstructured service is full-bandwidth 1.544 Mbps (DS-1) and 2.048 Mbps (E1) clear channel service per port. Channel-associated signaling (CAS) and basic circuit signaling modes are supported with structured service.

Network modules are added to existing switch chassis to increase interface capabilities. Be sure that a slot is available in the switch chassis to accept the desired module(s). 2. Verify the current version of ForeThought software that is in use on the switch. 3. Select the network module(s) (below), verifying that the ForeThought software version from the Step 2 meets the minimum version requirements for the module. 4. If selecting the NM-1/2488 network module, order a minimum of one SCP (minimum 266 MHz) to power the module/fabric; order two SCPs if SCP redundancy is required in this module/fabric.* 5. Order additional replacement or support services from the Services ordering information (see next page) for each network module ordered. Marconi’s standard one-year warranty provides return-to-factory (RTF) replacement within 10 business days. A wide portfolio of optional advisory and replacement services is available. 6. Order network module cables as needed. (Network modules and appropriate cables are listed on the following page.) Note that cables are for a single port.
