10.Determine which type of configuration is best suited for your system. Some guidelines for selecting the service configuration are shown below:

■IOC capability package “S”

Each BRI line, also called a Digital Subscriber Line (DSL), consists of two B-channels, both of which support voice and data calls. In order to have two simultaneous voice or digital data calls, each DSL must be assigned two Directory Numbers (DNs) and two Service Profile Identifiers (SPIDs) by the CO. Basic call handling is supported along with the Calling Party Number/Billing Number (CPN/BN) identification feature. No packet data capabilities or hunting features are provided.

NOTE:

On the Lucent Technologies 5ESS switch, the Calling Party Number identification feature is assigned using the standard BRCS preconstructed features /LICNDA and /CPCOFA. If it is possible, request /CPCPFA for the Calling Number Identification feature from your local service provider as it provides a clearer display of the CPN information.

IOC package “S” supports a maximum of one call per telephone number (DN) at any given time. If another call comes in on that line, the caller gets a busy signal.

For Canada and those areas of the United States where IOC package “S” is not available, the capability package that is ordered must provide alternate voice/circuit-switched data on both B-channels with no packet data capability or supplementary voice features except for the CPN/BN feature if available. See Appendix H, “NI-1 BRI Provisioning” for detailed information.

■Multiline Hunt (MLH)

This feature is not part of the IOC package “S” and must be provisioned separately.

One or more BRI lines (and their associated DNs) are grouped together with one (main) telephone number. When an incoming call arrives at the main number, the CO searches through the DNs until an available line is found.

NOTE:

Each DN in the MLH group can be dialed directly, but hunting may not be initiated (depending on the CO switch).

For the Siemens SSD EWSD switch, each MLH group must be assigned as either voice or data; alternate voice/data is not supported as mixing the two types in one group could create call interference. This constraint does not apply to the Lucent Technologies 5ESS or the Northern Telecom DMS-100 switches.
