5ESS Features
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
• Accept special type of number
