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. However, if you use a multipoint line, the parameters are similar to the point-to-point lines, except for the SPIDs.

The 5ESS switch can provide a variety of supplementary features which the ISDN TA may not support. Enabling these features may have undesirable consequences.

Features to avoid are:

•Packet mode data

•Multiline Hunt Groups

•EKTS (Electronic Key Telephone Set)

•Shared directory numbers

•Intercom groups

•Modem Pools (Network resource selector)

•Message waiting

•Hunting

•Inter LATA competition

•Accept special type of number

10b. DMS-100 Pvc1 Line Additional Parameters

The Northern Telecom DMS-100 telephone switch supports a proprietary ISDN D-channel call control protocol called Protocol Version 1 ("Pvc1") which is based on CCITT recommendations. The ISDN TA configured for switch type DMS-100 will work with lines providing this protocol on DMS-100 switches with software version BCS-32 or later.

The ISDN TA supports the following configurations on DMS-100 Custom lines:

•Multipoint with one phone number (for 1 B+D service)

•Multipoint with two phone numbers (for 2B+D service)

The requirements for the DMS-100 multipoint line are defined in Local Interface Requirements, Local Service Requirements, and below. Fax this information to your local phone company.

The line should have two service profiles with the parameters below, to support BONDING and the POTS port, if installed.
