Newbridge Alcatel 90-6184-13/D Newbridge 3600 MainStreet WAN switching Telecom System Card / Module

The Newbridge Alcatel 90-6184-13/D carries the marking ISC and nothing more. As with several Newbridge abbreviations, ISC does not appear in any published reference we could verify, so while the 90- numbering places the card in the MainStreet range we are not able to say what it does. The /D suffix is a build marker. We hold the board and will read its legend and revision for you before anything is quoted.

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.
