Model No. Running Head SRU Card Specifications SRU Card
5. If necessary, also perform loopbacks and send test signals to the affected circuit from
the other end. In addition, you can perform end-to-end tests using a suitable data test
set at one or both ends of the circuit in conjunction with the loopback functions of the
SRU card at either end.
6. If the SRU card is determined to be faulty, replace it and return the faulty unit for repair
to the location specified by your distributor.
