Newbridge 90-2517-33/H 3600 MainStreet WAN switching Telecom System Card / Module

The Newbridge 90-2517-33/H is a circuit emulation card recorded as E1CE. Circuit emulation is what let a MainStreet ATM switch carry a conventional 2 Mbit/s E1 circuit across a cell based network transparently, so the equipment at either end saw an ordinary leased line. Other suffixes under this same base number are documented as the T1 version of the same card, which fits the E1 and T1 pairing Newbridge used throughout the range.

Newbridge Networks built the MainStreet range of multiplexers and switches, later sold under Alcatel after the 2000 acquisition, and the 90- prefixed numbering identifies cards, shelves and cables across that range. The 36170 MainStreet Xpress ATM switch and the 36120 and 46020 multiplexers took interface cards for E1, T1, T3, E3 and circuit emulation, with a control card at the centre of each shelf. The platforms are out of support and maintained from held stock.
