SRS -1050 Installation (

Appendix B

The Sharing Terminal Identifier, component two, differentiates between terminals that share the same main telephone number but have different services on the ISDN line. For a terminal that does not share the same main telephone number, these digits are “01”. This is the typical situation.

The last part of the SPID is another two digit segment. This terminal identifier differentiates between terminals that share the same main telephone number and have identical services. In typical situations, these digits are “01”.

The most frequently assigned SPID will be the following: NPA NXX XXXX 0101.

If your service provider has not supplied a SPID to you, try this format shown above. If it does not work, contact your service provider or System Administrator.

Occasionally, if the switch is very busy, the download may be delayed for a short time. The SRS-1050 will continue to request a download until it is successful, or until it receives a message from the switch indicating that a manual configuration is needed.

The SRS-1050 also supports two other functions associated with parameter downloading.

1)Service Profile Change Notification. If you request a change to your ISDN service configuration, when that change is completed in the central office, the switch notifies the SRS-1050 that a change has occurred. The SRS-1050 then requests a download from the switch to update its configuration. This occurs automatically.

If you have used the manual configuration feature, the settings that differ from the downloaded settings will be lost.

Note: On a DMS-100 which supports SPM instead of parameter downloading, if a Service Profile change is made in the switch, it is necessary to unplug the set from the power and reconnect it in order for a download of the new configuration to occur.

2)The SRS-1050 provides a manual download function that allows you to request a download if you suspect that the information in the SRS- 1050 may be corrupt. Instructions for manual download are in the Key Attribute section.
