Looking for pin lay-out of PRI interface on BTU-D card (BP250) - PBX Info :: Your Free PBX, PABX and Telephone Information Resource

Hi,

I'm trying to put an ISDN switch between our BP250 and the regular ISDN line. Can somebody provide me with the exact pin lay-out of the PRI connector on the BTU-D card please ( E1 PRI Q.931)

(Does anyone know how these connectors are called by the way? They look very standard connectors for telephony purpose, but I need a standard name so I can make a kind of a split cable )

Many thanks

Here it is.

Most of the connectors on the BP series of cards are of the type RV100.
In real standard terms are they referrred to as
DIN 41612 ( aka Eurocard ) connectors.
Cannon ITT used to sell the E2X series of connectors which fully comply with these.
AMP (Tyco), ENRI and a lot of others have similar connectors which comply.
Maybe interesting for those who want to make their own cables.

Cheers
