Caller Identification
Strata CTX General Description 10/04 61
Caller Identification
Caller Identification (Caller ID) is the general term for the information provided identifying the
originating party of a public network call. The name and telephone number of the calling party
displays on the ringing telephone’s LCD. Incoming calls with Caller ID or Automatic Number
Identification (ANI) information may be optionally recorded into a rolling list for individual
stations. Station users with LCD displays can access this list to select and redial these calls (see
Call History). Caller ID service from the carrier must be subscribed on analog CO lines or T1 ANI
in order to receive calling number and name into the Strata CTX system.
Caller ID lists can include the number, name (if provided), time and date of the call, and status of
the call (answered, abandoned, or redirected). Digital stations are assigned memory for creating
the Call History. See
Table 12 on page 26 for the number of call records per station and system.
ISDN Calling ID Name and Number
System Availability: Strata CTX100, CTX670
Both Caller ID name, if available from service provider, and number are supported for incoming
calls using either ISDN NI-1 or NI-2 BRI or PRI lines. Caller ID names can be accepted by the
Strata CTX from a CO with NI-1 or NI-2. NI-2 is the only way a 5ESS CO delivers Caller ID
names on PRI and BRI. Nortel DMS CO with NI-2 installed also uses NI-2 to deliver Caller ID
names. Only a Nortel DMS CO can provide Calling Names for NI-1.
Camp on Busy
System Availability: All systems
Automatic Camp On
When a call comes in to a busy station from an outside line and that station does not have an idle
button for the call to ring in on, and Station Hunting or Call Forward is not applied, the call
automatically camps on to the busy station. This permits incoming calls to be accepted even if the
station is busy. The outside caller will receive ring-back-tone immediately and the called station
will receive two bursts of Call Waiting tone.
If the calling line has Caller ID, ANI, or DNIS information, it will be displayed on the called
station’s LCD for 10 seconds. Auto Camp On also applies to incoming line calls directed to Hunt
Groups, Voice Mail systems, etc.
Various types of internal calls from one station to a busy station, voice mail system or hunt group
can also Camp On automatically with system programming options. For details on these types of
calls see the Camp On-Busy and Station Hunting descriptions.
Off-hook Camp On
A station caller who dials a busy station or line access code can remain off-hook to be
automatically connected when the station or line becomes idle. After dialing a busy [DN] and
receiving busy tone, the caller can just remain off-hook and Camp On will be initiated
automatically after a predetermined time or the user can dial a
1 and remain off-hook to initiate
Camp On immediately. When camp-on is activated, the caller will receive success tone followed
by Ring Back Tone. The station that is the object of a camped-on call will receive two bursts of
call waiting tone (see Call Waiting).
