9. Contact the local service provider and determine what type of CO switch
serves your area (such as, AT&T 5ESS, Northern Telecom DMS-100, or
Siemens SSC EWSD). Enter this information under the Type of CO Switch
heading on page 2 of the form.
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 AT&T 5ESS switch, the Calling Party Number identifi-
cation feature is assigned using the standard BRCS precon-
structed features /LICNDA and /CPCOFA. If it is possible,
request /CPCPFA for the Calling Number Identification fea-
ture 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 tele-
phone 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 supplemen-
tary voice features except for the CPN/BN feature if available.
See Appendix H, "NI-1 BRI Provisioning" for detailed informa-
tion.
Multi-Line 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).
