The Nortel NTHW91AA is a 2-port DS3 Channelized CES module for the Nortel Multiservice Switch 15000 platform, part of the established NTHW function-processor family.

The Nortel NTHW91AA is a 2-port DS3 Channelized Circuit Emulation Service (CES) module for the Nortel Multiservice Switch 15000 (MSS 15000) platform, part of the documented NTHW-prefixed function-processor family used across the Passport/MSS 15000 and MSS 20000 range. Channelized CES modules split each DS3 trunk down into its constituent DS0/DS1 channels and carry them as emulated circuits across the switch’s ATM or IP core, letting a carrier keep TDM voice and data services running over a packet-based backbone. The MSS 15000 chassis accepts a wide range of these function-processor cards to configure each network element for its required port mix and service type, and genuine spares are a routine requirement for carriers still running this transport layer. Tech-Star (UK-based, shipped worldwide) stocks Nortel MSS 15000 cards to support ongoing network maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
