STATE

The State setting determines whether the port is active or inactive. An inactive port does not occupy time slots on a WAN link. Set State to standby (stdby) for ports you are not using or have not yet configured. Set it to active (actv) for ports that are ready for use.

Format

The format setting determines the type of framing to be used on the individual port, either d4 or esf.

Line LB

The Line Loopback setting controls looping of the full T1 line back to the network. When on, this setting allows end-to-end testing of the line.

LOCAL LB

The LOCAL Loopback (LOCAL LB) option activates a loopback on the selected port. Choose the on setting to loop the outgoing data from the external TPE device back to the TPE receiver. This loopback allows you to check the local cabling and most of the optical circuitry in the OWAN port. It also disconnects the incoming data from the far end.

LB GEN

Currently the loopback generate function has not been implemented. When done, the loopback generation field enables the OWAN to generate a loopback request when set to on. Otions that will be supported are the plb (payload loopback) and llb (line loopback) when is esf format. For d4 format, the values will be loop-upand loop-dn. No loopback and the default are set to

off.

LB DET

Currently the loopback detect function has not been implemented. When done, the loopback detect field enables the OWAN to detect a loopback code request when set to on. It also provides a with time out w/to option, which will detect and enter into a loopback state, but drop the loopback after 10 minutes.
