Dave, We have a similar problem on an E1 application (PRI physical layer). BABT has permitted us to use the simple and inexpensive expedient of looping XMT back to RCV through a 10 dB attenuator. If we get error-free operation (no alarms), then we have proved receiver sensitivity to BABT's satisfaction. I don't know if they would accept this solution in a BRI application, but you might give them a call to inquire.

We manufacture BRI cards for the european market and BABTstipulate, as part of their PQAA procedure, that all boards produced must be subjected to receiver sensitivity testing. The problem with the K1403 is that it is expensive (it does after all fully test Net 3 layer 1 ) and test throughput is slow. At present we hire a K1403 when we have a production batch ready to test. We are looking at designing our own test equipment but this is not trivial. We also looked at pursuing the BABT sampling scheme as an alternative to being a PQAA site but decided we would rather keep things in house. I would appreciate any input on this. regards David Sanderson Aculab plc [email protected] ---------------------------------------------------------------------------- Peter Van Raalte | Email: [email protected] Compliance Engineer | V-Band Corporation | Phone: 914-789-5117 565 Taxter Road | Elmsford NY 10523 | FAX: 914-347-3432 ---------------------------------------------------------------------------
