[asterisk-users] E1 crossover system

[Paul Hales]

I am setting up an E1 crossover system for a customer, with a Siemens
Hipath Officecom 150 system.

And it's not working - I get a red alarm from the outside world, and a
yellow from the PABX.

Any ideas? We have tried E1 crossovers and straight cables on both
connections, with no more luck.

Frame type? Cabling? Timimg?

Any ideas at all? Anyone?
