The two Port OC-12/STM-4 Trunk Module delivers SONET/SDH WAN connectivity to any MD8000 chassis, including the MD8000, MD8000EX, and MD8000SX. Ethernet packets are used to efficiently transfer data to/from this trunk module to the device’s redundant switch controllers over a non-blocking Layer 2 Switch Fabric. This trunk module has the capability of handling Jumbo frames (up to 9022 bytes in length including headers and FCS).

Two ports operating at 622Mbps (581.068 Mbps effective) are built into the OC-12/STM-4 Trunk Module. For improved network utilization and multi-service termination onto a single trunk port, the OC-12/STM-4 Trunk Module supports several different SONET/SDH concatenation modes, including full, four-division, port 1 full and port 2 twelve division, and port 1 twelve division and port 2 full.

The 2 Port OC-12/STM-4 Trunk Module accepts small form factor pluggable [SFP] optics to support optical budgets of 10km, 40km, 80km and 120km. To assist in SONET/SDH installations and troubleshooting, a complete set of status/diagnostic LEDs and counters are featured. Support for ITU-T G.7041, Generic Framing Procedure (GFP), permits easy IP network integration.
