I have the polycom Quad BRI TA, however i am getting no connectivity between the to, I have set the OS Bri module to S0 Bus (exts). Has anyone connected these two before ? Is there an issue where the polycom maybe looking for ISDN timing, but the S0 bus isnt providing timings ? Adam

(labeled P1-S, P2-S, and so on) and have switched on the dip switches to enable the 50ohm terminating resistors? Done all the required programming in the MMC's?
