ISU 512e User Manual

IF THE DISPLAY READS SPID<1,3,5, OR 7>

If the ISU 512e reads 

SPID1

, then the ISU 512e is physically connected 

to the local telephone service provider and has established Logical 
Layer 2. The ISU 512e is unable to establish Layer 3. The problem is 
with one or more of the following:

•

The ISU 512e software setup

•

The software setup of the telephone service provider

To isolate the problem, use the following procedure:

1.  Ensure the ISU 512e is set up for the correct switch protocol.
2.

E

nsure that the ISU 512e is set up with the correct SPIDs and 

LDNs. Review ISDN Menu/SPID on page 6-3. 

3.

Connect another piece of functioning ISDN equipment to the 
ISDN line.

4.

With the ISU 512e connected to the ISDN line and powered up, 
talk to your service provider's repair group and inform them you 
have an ISDN basic rate line that appears physically OK but has 
no Terminal Endpoint Identifier (TEI). Ask them to check the 
ISDN line translation and ensure that the line supports dynamic 
TEI allocation. Inform them that an NT1 and terminal adapter 
device are connected to the ISDN line.

IF THE DISPLAY READS SPID<2,4,6, OR 8>

If the ISU 512e continues to read 

SPID2

, the ISU 512e has completely 

initialized the first phone number but is unable to establish Logical 
Layer 3 for the second phone number. The problem is with one or 
more of the following:

•

The ISU 512e software setup

•

The software setup of the telephone service provider

To isolate the problem, perform the following procedure.
