Caller Id; Figure 1-2 Left Cursor Key Operation Flow Chart - NEC SL1000 Features And Specifications Manual

SL1000
Description
Caller ID allows a display terminal to show an incoming caller's telephone number (called the Directory
Number or DN) and optional name. The Caller ID information is available as pre-answer display. With
the pre-answer display, the user previews the caller's number before picking up the ringing line.
On the CPU with MEMDB for Caller ID (also used for DTMF receivers and Call Progress Tone Detection) 36
resources are available. Each EXIFE provides an additional 32 resources.
Second Call Display
C
While busy on a call, the telephone display can show the identity of an incoming trunk or Intercom call.
For incoming trunk calls, the display shows the Caller ID or the trunk name if Caller ID are not
installed. For incoming Intercom calls, the display shows the calling extension name.
Caller ID supports the Telco Called Number Identification (CNI) and Called Number Delivery (CND)
service, when available.
The telephone display can show up to 12 Caller ID digits.
Once installed and programmed, Caller ID is enabled for all trunk calls, including:
• Ring Group calls
• Calls transferred from another extension
• Calls transferred from the VRS
• Calls transferred from Voice Mail (unscreened)
• Direct Inward Lines (DILs)
Caller ID temporarily stores 50 calls (total of abandoned and answered/unanswered). New calls
replace old calls when the buffer fills.
Temporary Memory
An unanswered call causes the Call History key (Program 15-07 or SC 851 : 08) to flash, indicating a
new call was placed in the temporary memory. If enabled in programming, the telephone display
shows CHECK LIST.
This Caller ID data from the temporary memory can be saved in either Speed Dial bins or in
One-Touch keys making them available for placing future calls.
Cursor Key Operation (When set PRG15-02-60:0)

By pressing the Left Cursor Key the user can access the Redial and Incoming Call History menus. The
