Jack For Primary Operator Position - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Numbering the System
To calculate the total number of TTRs that are required by the system, do the
following:
1. If the system has a VMS, use Table 2–3 to find the number of TTRs
required by the system to support the VMS. If the system does not have a
VMS, then proceed to Step 2.
2. Estimate the hourly call volume for all calls originating from single-line
telephones, incoming calls on Remote Access, DID lines, T1 data lines,
and calls on tie lines.
3. Use Table 2–4 to find the system requirements for TTRs based on the
hourly call volume estimated in Step 2.
4. If the system has a VMS, add the TTRs required for the VMS (Step 1) to
the system requirements for TTRs (Step 3). This is the total number of
TTRs required for the system.

Jack for Primary Operator Position

The factory setting for the primary operator position is the lowest extension jack
on the first MLX or analog multiline telephone module. You cannot change the
factory setting for the primary operator position.
The primary operator position uses two types of operator consoles:
Direct-Line Console (DLC). Can be assigned to either a digital or analog
extension jack.
Queued Call Console (QCC). Can be assigned only to a digital
extension jack, and the MLX-20L is the only telephone that can be used
as a QCC.
If the system includes QCCs, the primary operator position must be a QCC.
