Multipoint lines require the phone company to create a SPID for each phone number on the line. With the exception of the ability to spread two calls across two phone numbers, multipoint lines offer no special features, and may create complications. How- ever, if you use a multipoint line, the parameters are similar to the point-to-point line, except for the SPIDs.

The 5ESS switch can provide a variety of supplementary features which the ISU 2x64 may not support. Enabling these features may have undesirable consequences. Avoid the following fea- tures:

Packet Mode Data

Multiline hunt groups

Electronic key telephone set (EKTS)

Shared directory numbers

Intercom groups

Network resource selector (modem pools)

Message waiting

Hunting

InterLATA competition
