YELLOW

Flashing once every two seconds indicates loop synchro- nization has been established, but carrier synchronization has not.

Flashing twice every second indicates carrier synchroniza- tion has been established, but loop synchronization has not.

Indicates that Layer 1 is established from the ISDN switch to the customer ISDN terminal equipment.

Solid when a front panel test has been initiated or when responding to 2B+D loopback request.

Flashes once every two seconds when responding to a B1 loopback request.

3 Insert U-BR1TE card into a TA 750 chassis slot 1-6, TA 850 chassis slot 1-6, or TA 1500 chassis slot 1-24. To insert, hold the U-BR1TE card by the faceplate while supporting the bottom edge of the card. Align the card edge with the guide groove in the TA 750/850/1500 chassis. Insert into chassis until the edge card co- nector seats firmly into the chassis backplane. Lock the unit in place by pushing in on the locking lever.

Provisioning - The TA 750/850/1500 supports two types of provisioning

 

modes, local and remote. Local provisioning results in the unit operating

 

as defined by the on board switches. Remote provisioning, if chosen,

 

results in the unit operating as defined by the system controller menu set-

 

tings (on-board switches are ignored). The operational mode is indicated

 

by the REM LED and can be changed by activating the AP (Alternate
