TEL – Screen 1: Status
In ISDN or V.35 mode…
…
This screen shows the status of each of the two ISDN B channels. The status will vary depending
on the Interface selected in the ISDN Menu, and can be as follows:
Status words when ISDN Interface is selected:
Inactive – This indicates that neither the built‐in NT1 nor the S interface is active. This
will be displayed if no ISDN line is present. It is also displayed on ETS 300 (Euro‐ISDN)
lines after periods of inactivity (the ETS 300 standard allows the central office switch to
put the line to sleep).
SPID Pending – This option is only valid when the Telco selection of the TEL menu is set
to “Natl.I‐1” or “DMS Cust.”. This indicates that the Xstreams internal NT1 has achieved
"U synchronization" with the BRI circuit, or that the S interface connection to the
external NT1 is active. This also could be displayed if the BRI is grossly misconfigured.
