Newbridge 90-5947-22 3600 MainStreet WAN switching Telecom System Card / Module

The Newbridge 90-5947-22 shares its base number with another TE3-2 card in our stock and differs in the trailing digits, which in Newbridge numbering separate builds that are visually identical. The card handles the T3 and E3 tier, the 45 and 34 Mbit/s rates above the shelf’s E1 and T1 circuits, and is recorded with its medium attachment unit. Builds within one base number are not always interchangeable, so tell us which one your shelf is running.

MainStreet was Newbridge’s flagship product family, covering narrowband multiplexers and later the 36170 ATM switch, and it stayed in service under the Alcatel badge well past the acquisition. Shelves are filled with interface cards chosen for the circuit types a site terminates, and the trailing digits on a 90- code separate variants that look identical on the front panel. Matching the whole code is how you avoid a card that will not commission.
