5.4 Troubleshooting ISDN Problems
Status Screen for ISDN troubleshooting
This screen shows the status of the ISDN connection. You can determine if the line is connected and
whether the line and the Telos device are successfully configured. In addition, information about calls is
displayed here. One of the following status words will be shown for each active ISDN channel:
Deactivated
No line connected, or connected to wrong jack on the Telos. OR, ETS 300 permits the Telco to put a line to
sleep. Deactivated will be displayed when this occurs.
SPID Pending
The SPID has been sent to network (DMS Cust. And Natl I-1 only). Network has not approved SPID.
SPID Error
The SPID is incorrect or line is grossly misconfigured
Ready
The unit sees a live ISDN S interface (ie external NT1 is present or internal NT1 has completed startup). If
the SPIDS are present, they have been sent and approved.
Pending Seize
Outgoing call in process; Request for call has been sent to Telco switch.
Seized
Outgoing call in process; Telco switch has acknowledged the call request.
Call Proceeding
Outgoing call in process; Telco switch waiting for routing info from network.
Outgoing Ring
Outgoing call in process; far end has generated a call alert signal
Disconnecting
Request to disconnect has been made. Awaiting acknowledgment.
Incoming Ring
An incoming call request has been detected and is being processed.
Accepting Call
iQ6 has accepted an incoming call and is waiting for the Telco switch to connect it.
Connected
All signaling is complete - the voice channel is available for use.
A caveat regarding the Ready indication: If you have this indication with the iQ6 Telco mode set to AT&T
Cust and you cannot dial, it is likely that your line is Natl. I-1 or DMS-100. The AT&T Custom PTP protocol
does not require SPIDs, so the iQ6 does not send or check them; it just assumes the line is OK in this regard,
so it gives the ready indication, though the line is actually waiting for the SPIDs.
