Multipoint Configurations

In older ISDN installations, most phone connections are point-to-point. Each phone in a point-to-point configuration requires a separate line into your building. However, most service providers now offer multipoint configurations as a subscription option. In a multipoint configuration, up to eight devices (digital sets and/or terminal adapters) can be connected to a single line. For example, your company could connect two digital sets and two data terminal adapters to a single line. The two digital sets could each use one B-channel for voice communication, and the data terminal adapters could use the D-channel for packet-switched data calls.

SPID

For your SRS-2100 to work, it must have a valid Service Profile Identifier (SPID). (If your SRS-2100 is the voice/data version, you need two SPIDs, one for voice and one for data.) The SPID number is usually entered when the SRS-2100 is installed. So if your digital set already has a SPID number, you don't have to reenter it. If you do need to enter a SPID number, you can find out what it should be from your System Administrator or service provider. For the procedure to enter a SPID, see Appendix B.

CAUTION: Once the SPID number is entered, don't change it unless your System Administrator tells you to do so. Your SRS-2100 won't work without the correct SPID number. If the SPID number is wrong, the set displays the message SPID NG. (The message is redisplayed a second time if the data terminal adapter SPID is also invalid.) Enter the correct SPID number and you'll get the normal dial tone.
