TN2238

The TN2238 is not supported with DEFINITY ECS R8 and later systems.

TN2238 ATM circuit packs replace TN570B/C Expansion Interface circuit packs when ATM is used for the Center-Stage Switch of a Port Network (R7r only), and they support ATM trunking and wide-area network (WAN) connectivity (for ATM Circuit Emulation Service, see TN2305). The TN2238 can be connected to an ATM-based Center-Stage Switch or an ATM network. It uses standard, multi-mode, 155.52-MHz, OC-3c fiber.

Up to 2 TN2238 ATM port-network expansion interfaces can be installed per carrier.
