Appendix F: Ordering ISDN Without IOCs

After Service Is Installed

When the line is installed, the following information will be pro- vided by the local phone service provider:

•A seven-digit LDN for the line. If the line is multipoint with two phone numbers, two LDNs are provided.

•If the line is multipoint, a SPID is provided for each LDN.

•Dialing information, including the area code, for the line.

•Any special instructions for dialing outside lines, dialing 4- digit local extension numbers, and prefixes for using the de- sired long distance provider.

SETTING UP THE ISU 2X64 FOR A NEW LINE

1.Disconnect the ISDN line from the ISU 2x64.

2.Turn on the ISU 2x64, verify that it passes self test.

3.Turn off the ISU 2x64; while holding down 0, turn on the ISU 2x64. Continue to press down 0 for 15 seconds. This will re- set all the internal settings to factory defaults.

4.The ISU 2x64 is now set up for 5ESS Custom. If this is not the correct line-type, select CONFIG, Netw. Options, Dial Line, Switch Type, and the desired switch type.

5.Enter the SPIDs and LDNs for the ISDN multipoint line. Se- lect CONFIG, Netw. Options, Dial Line, Terminal ID, Set SPID/Set LDN and enter the SPIDs and LDNs. Make sure that SPID1 corresponds to LDN1 and SPID2 corresponds to LDN2.

6.Turn the ISU 2x64 off for 2 seconds, then on. This is required after changing any of the previous settings. The ISU 2x64 should now be set up for your ISDN line. You may wish to verify the settings.

7.Connect the ISDN line to the ISDN IFC connector on the ISU 2x64. The front panel should read Link Down and progress to Ready as the line is activated. This process may take a minute.

At this point, if the ISU 2x64 does not read Ready, see the section If the ISU 2x64 Does Not Read Ready in the chapter Troubleshooting.
