NI-1 BRI Review
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 AT&T 5ESS or the Northern
Telecom DMS-100 switches.
The administration for Multi-Line Hunt is CO switch dependent. The
AT&T 5ESS and Siemens SSC EWSD switches provide hunting
through the Series Completion feature. The Northern Telecom
DMS-100 switch provides hunting through the Multi-Line Hunt Group
(MLHG) feature. Contact the local service provider to determine what
type of switching equipment is in use and check the appropriate box
under the MLH subheading of the Service Configurations section on
page 2 of the form.
The MERLIN LEGEND has currently been tested with each switch
type in the following configurations:
Other configurations are possible, but are not guaranteed to work.
Appendix H, "NI-1 BRI Provisioning" provides sample LEC
administration screens of the Series Completion and MLHG features.
These screens show the fields and parameters for the CO switch and
may be forwarded to the local service provider if necessary.
11. Once you have determined your Service Configuration, do one of the
following:
If your Service Configuration will be IOC "S", check the box beside the
IOC "S" selection under the Service Configuration heading, then enter
the number of BRI lines that will be provisioned using this package.
If your Service Configuration will be MLH, check the box beside the
MLH selection under the Service Configurations heading.

AT&T 5ESS in a linear hunt group
Northern Telecom DMS-100 in a circular hunt group
Siemens SSC EWSD in a circular hunt group
Indicate the type of MLH configuration by checking the box for
MLHG (Northern Telecom DMS-100) or Series Completion (AT&T
5ESS or Siemens SSC EWSD).
Enter the total number of BRI lines provisioned using MLH, the
number of BRI lines provisioned as voice only hunt groups, the
number of BRI lines provisioned as data only hunt groups, and the
number of BRI lines provisioned as voice/data hunt groups in the
spaces provided.
NOTE:
MERLIN LEGEND Release 4.0 does not support voice/data hunt
groups with the Siemens SSC EWSD CO switch.
