							Call Waiting / Camp-On
DS2000 Software ManualChapter 1: Features53
Split (Alternate) (page 272)
Camp-On lets an extension user know that a call is waiting to be answered. The user can Split 
between the waiting call and their current call.
Transfer (page 324)
An extension user may be able to Transfer a call to a busy extension.
Trunk (Line) Queuing / Trunk Callback (page 332)
Trunk Queuing lets an extension user Camp-On to a busy trunk.
Volume Controls (page 353)
The extension user cannot adjust the volume of incoming Camp On tone.
Feature Operation
To Camp-On to a busy extension:
1. Call busy extension.
2. Dial 2; do not hang up.
If you hang up, the system converts your Camp-On to a Callback.
3. When your co-worker hangs up their initial call:
4. Speak to your co-worker when they answer their Camp-On ring.Busy tone.

							Callback
54Chapter 1: FeaturesDS2000 Software Manual
Callback
Description
When an extension user calls a busy co-worker, they can leave a Callback request for a return call. 
The system services Callback requests as follows:
Caller at extension A leaves a Callback at extension B.
Caller can place or answer additional calls in the mean time.
When extension B becomes idle, the system rings extension A. This is the Callback ring.
Once caller A answers the Callback ring, the system rings (formerly busy) extension B.
If caller A doesn’t answer the Callback ring, the system cancels the Callback.
As soon as caller B answers, the system sets up an Intercom call between A and B.
An extension user can leave a Callback at many extensions simultaneously. The system processes 
the Callbacks as the extensions become free. In addition, many extensions can leave a Callback at 
the same extension. The system processes these Callbacks on a first-in/first-out (FIFO) basis.
If an extension user leaves a Callback request and then fails to answer within four rings, the system 
cancels the Callback.
Conditions
A system reset or power failure cancels all Callbacks system-wide.
Default Setting
Callback enabled.
Programming Guide
LCCPU 01.00.00 Available.
With Callback, a user does not have to repeatedly call a busy extension back, hoping to find it idle.

Programming Guide
Step-by-step guide for setting up Central 
Office Calls, Answering (Page 1 of 3)
Step 1: Check to be sure each trunk’s circuit type and loop length setting matches the con-
nected trunk circuit.
• In Program 1001 - Trunk Circuit Type (page 416), 
enter the correct circuit type for each trunk (51 = 
loop start DTMF, 52 = loop start DP).
• In Program 1001 - Loop Length (page 420), use 
this option to compensate for a trunk’s loop 
length. Use the short option (1) only when the 
system is very close to the central office or behind 
a PBX. Use the long option (2) for normal instal-
lations.
Step 2: Review System Timers, Trunks on page 300 for compatibility with the connected telco or 
PBX/Centrex.
Step 3: Set the trunk access options at each extension for each trunk.
• In Program 1803 - Extension Line Access Assign-
ments (page 461), enter 0 to prevent both incom-
ing and outgoing access on the trunk.
• In Program 1803 - Extension Line Access Assign-
ments (page 461), enter 1 to allow incoming 
access only.
• In Program 1803 - Extension Line Access Assign-
ments (page 461), enter 2 to allow outgoing 
access only.
• In Program 1803 - Extension Line Access Assign-
ments (page 461), enter 3 to allow full access 
(both incoming and outgoing).
Step 4: Set the ringing options at each extension for each trunk.
• In Program 1805 - Ring Assignment (page 466), 
enter 1 for each trunk that should lamp only (day 
and night).
• In Program 1805 - Ring Assignment (page 466), 
enter 2 for each trunk that should ring during the 
day and at night.
• In Program 1805 - Ring Assignment (page 466), 
enter 3 for each trunk that should ring at night and 
lamp only during the day.

• In Program 1805 - Ring Assignment (page 466), 
enter 4 for each trunk that should delay ring dur-
ing the day and at night.
•InProgram 0401 - Trunk Delay Ring (page 376), 
enter the interval after which a delay ring trunk 
will change from flashing to ringing.
Step 5: Should extension have line keys for answering trunk calls?
• In Program 1701 - Line Key (page 436), assign 
programmable keys as line keys (code 03). The 
options are 01-16 (trunks 1-16).
• In Program 1701 - Line Key (page 436), make 
sure no keys are assigned as line keys (code 03).
• In Program 1701 - Switched Loop Key 
(page 436), or in Program 1701 - Fixed Loop Key 
(page 436), assign a loop key to any extension 
without line keys. This allows the extension to 
answer trunk calls.
Step 6: Should DSS Console have line keys for answering trunk calls?
• In Program 1704 - Line Key (page 444), assign 
programmable keys as line keys (code 03). The 
options are 01-16 (trunks 1-16).
• In Program 1704 - Line Key (page 444), make 
sure no keys are assigned as line keys (code 03).
Step 7: While on a trunk call, is a user’s conversation transmitted to the caller at a confort-
able level?
• In Program 1001 - Trunk Transmit Gain 
(page 417), leave this option at its current setting.
• In Program 1001 - Trunk Transmit Gain 
(page 417), increase or decrease the trunk trans-
mit gain for the optimum transmission level for 
the connected telco or PBX.
Step 8: While on a trunk call, is the conversation received by the user at a comfortable 
level?
• In Program 1001 - Trunk Receive Gain 
(page 419), leave this option at its current setting.
• In Program 1001 - Trunk Receive Gain 
(page 419), increase or decrease the trunk receive 
gain for the optimum reception level for the con-
nected telco or PBX. Step-by-step guide for setting up Central

Programming List
Program 0401 - Trunk Delay Ring (page 376)
Set how long the system flashes a line key before ringing an extension that has the Delayed 
Ringing option enabled.
Program 0402 - Minimum Ring Detection Timer (page 380)
Set the threshold for ring detection. If the ring signal is longer than this interval, the system 
interprets the signal as valid ringing. If the signal is equal to or shorter than this interval, the 
system ignores the ringing.
Program 0402 - Loop Current Detection Time (page 382)
Set the loop disconnect interval for trunk calls. If the system detects a loop current interrup-
tion longer than this interval it assumes the telco has disconnected the trunk. It then returns the 
trunk trunk to idle.
Program 0402 - Ringing Signal End Detect Timer (page 383)
If the ringing signal on a trunk call is interrupted for longer than this interval, the system 
assumes ringing has stopped and terminates the call. If this interval is set to short, valid ring-
ing will be inadvertantly cut off. If too long, the system will leave the call set up even after 
ringing has stopped.
Program 1001 - Trunk Circuit Type (page 416)
Set the trunk’s circuit type for compatibility with the connected telco or PBX. The options are 
51 (loop start DTMF), 52 (loop start DP), 53 (ground start DTMF) or 54 (ground start DP).
Program 1001 - Trunk Transmit Gain (page 417)
Set the trunk’s transmit gain to compensate for the transmit gain characteristics of the con-
nected telco or PBX.
Program 1001 - Trunk Receive Gain (page 419)
Set the trunk’s receive gain to compensate for the receive gain characteristics of the connected 
telco or PBX.
Program 1001 - Loop Length (page 420)
Use this option to compensate for a trunk’s loop length. Use the short option (1) only when 
the system is very close to the central office or behind a PBX. Use the long option (2) for nor-
mal installations.
Step 9: Does the system properly detect ringing trunks?
• In Program 0402 - Minimum Ring Detection 
Timer (page 380), leave this option at its current 
setting.
• In Program 0402 - Minimum Ring Detection 
Timer (page 380), set the ring detect threshold for 
compatibility with the connected telco or PBX.
Step 10: Do trunks inadvertantly disconnect while users are on a call?
• In Program 0402 - Loop Current Detection Time 
(page 382), set the loop disconnect interval for 
compatibility with the connected telco or PBX.
• In Program 0402 - Loop Current Detection Time 
(page 382), leave this option at its current setting. Step-by-step guide for setting up Central
