Central Office Calls, Answering
Description
The system provides flexible routing of incoming CO calls to meet the exact site requirements.
Answering Priority
When multiple calls ring an extension simultaneously, the system services the ringing calls in the follow-
ing order:
1. Ringing Intercom call
2. Line or loop key (from lowest to highest)
Overflow
Refer to Overflow for Key Ring Calls (page 214) for details on the overflow options.
Single Ring Option for Single Line Sets
The option 1403-02: Single Ring for Single Line Set (page 635) determines the type of ringing at analog sin-
gle line extensions. If enabled (Y), analog single line extensions always receive single ringing for outside
calls. (Certain analog single line devices connected to the system may require this type of ringing.) If dis-
abled (N), outside call ringing at analog single line extensions follows the ringing pattern of the line. For
example, if a line is ringing the system with two ring bursts, the single line extensions will follow the same
ringing pattern.
Conditions
• Per FCC regulations, do not set 3103-01: Transmit Gain (page 814) higher than 0 dB.
• None
Default Setting
• All extensions have full access on all lines.
• In DSX-40, lines 5-8 require the Expansion Board.
• Extensions have immediate day/night ring on all lines.
• Single line sets ring according to
2132-[01-64]: Line Ringing (page 764)
programming (just like
keysets).
• Lines 1-8 ring extensions on line keys 1-8.
The system allows outside calls to ring and be answered at any combination of system extensions.
