9. Contact the local service provider and determine what type of central office
switch serves your area (for example, Lucent Technologies 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, the central office must assign two
Directory Numbers (DNs) and two Service Profile Identifiers (SPIDs)
to each DSL. 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.
NOTES:
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''
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 central office 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 central office switch).
