Considerations
The CMS cannot be connected to a system that is in Behind
Switch mode.
The CMS can handle calls for up to 28 agents on up to 28
lines, and it can answer calls on two lines at the same time
with the same announcement.
There can be up to six agent splits with 28 agents per split.
Up to two CMSs can be installed on a system to handle a
second set of lines if a business requires more than 28 lines
or employs more than 28 agents.
CMS operates on an approved AT&T PC with MS-DOS,
version 3.3. The PC must be dedicated to CMS.
The CMS supervisor's console is the MERLIN II System
Display Console. CMS agents can have any MDX telephone
or any analog multiline telephone that can be used with the
system. CMS agent telephones must be connected to the first
58 telephone jacks on the control unit. (CMS allows only a
two-digit method to specify an extension number; jacks 59 to
144 are designated by four digits.)
The two CMS interface card ports on the PC must be
connected to two analog multiline telephone jacks on the
same analog multiline telephone module; these jacks must be
operator positions. If two operator position jacks are not
available on the same module, another analog multiline
telephone module must be installed in the control unit to
provide these jacks.
CMS lines/trunks can be loop-start, ground-start, T1 emulated
ground-start, or ISDN-PRI.
Up to four CMS external alerts can be used for agents and
supervisors. For example, an alert sounds if the number of
calls waiting to be answered nears a programmed threshold.
A MERLIN Attendant can be used to direct callers to the
appropriate CMS group.
