Call Type
All Basic Rate ISDN calls have a specific number type and numbering plan field indicated in the
call setup message to the public network peer. In certain cases, front-end equipment interfacing
with the ISDN user (CPE) peer requires a specific number type and/or numbering plan. In the
past System was unable to support this requirement because the number type and numbering
plan options were not programmable. Now the number type and numbering plan are
programmable per call type for each equipped primary rate module. The operation of this
feature is transparent to the user. Once the number type and numbering plan are programmed,
the Primary rate call setup message will include this information for each call.
Overlap Sending
The SPID/DN/TEI option applies only for BRI trunk ports only. Each BRI trunk can have up to 16
SPID/DN/TEI pairs.
• Directory Number (DN): (U.S. Only) Is the number. No DN numbers are assigned by
default.
• Service Profile Identification (SPID): (U.S. Only) Contains the bearer information so that
the CO can associate the number with a set of bearer types, The CO will reject calls to the
directory number based on the bearer types assigned to that number. This also allows the
CO to charge a higher rate for numbers that have more bearer capabilities (for example,
numbers which support data or video as opposed to just speech). No SPIDs are assigned
by default.
• Terminal Endpoint Identifier (TEI): Contains value that Network uses to identify the
terminal. This value can be fixed or automatically assigned by the Central Office. In a
point-to-point setup, there is only one TEI. In a point-to-multipoint setup, there is at least
two. For the US, each SPID/DN pair has an associated TEI. The default is set to
Automatic.
Some Central Offices do not allow 16 SPIDs, and some allow as few as six. Also, SPID/
DN/TEI pairs are only defined for North American ISDN switch types, so they are defined
only for the US Systems. Other countries do not support SPID/DN.
