Central Office Calls, Placing
Description
The system provides flexibility in the way each extension user can place outgoing trunk calls. A 
user can place a call by:
Pressing a Line Key
Any keyset can have line keys for one-touch access to specific trunks. See 
Line Keys on 
page 238 for more.
Pressing a Loop Key
Loop Keys provide a user with one-touch access to the assigned Loop Group. Loop Groups can 
consist of one or more Trunk Groups. See 
Loop Keys on page 242 for more.
Using Line Dial-Up
With Line Dial-Up, a user can select a specific trunk by pressing 
ICM and dialing the Line Dial-
Up code (#9) followed by the trunk number (
1-48 for trunks 1-48 in DS2000, 1-6 in DS1000).
Using Direct Trunk Access
Direct Trunk Access allows a user to access a trunk by pressing 
ICM and dialing the trunk’s 
extension number (e.g., 401 for trunk 1, 402 for trunk 2. etc.).See 
Direct Trunk Access on 
page 139 for more.
Dialing a Trunk Group Access Code
User’s can also place trunk calls by pressing 
ICM and dialing a Trunk Group Access Code (90-
98). See 
Trunk Groups on page 405 for more.
Trunk Group Routing
If the system has Trunk Group Routing enabled, user’s get the first available trunk when they 
press 
ICM and dial 9. See Trunk Group Routing on page 398 for more.
Expanded Dial Buffering (02.01.07 or Higher)
When placing a trunk call, extension users can dial an unlimited number of digits. Users are assured 
that they can use services such as telephone banking without encountering restrictions imposed by 
the telephone system. In software versions prior to 02.01.07, callers are restricted to dialing 32 dig-
its maximum if they dialed continuously.
Conditions
Systems using Trunk Groups or Trunk Group Access should use the hybrid FCC registration 
number (i.e., the number that ends in MF-E). Look at the label on the bottom of your equipment 
cabinet for more information.
Per FCC regulations, do not set 1001- Trunk Transmit Gain on page 499 higher than 0 dB.

Programming Guide
Step-by-step guide for setting up Central 
Office Calls, Placing (Page 1 of 5)
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 498), 
enter the correct circuit type for each trunk (51 = 
loop start DTMF, 52 = loop start DP).
• In Program 0402 - Codec Digitizing Method 
(page 463), be sure to always set this option to 0 
(µ-law companding enabled). Do not set this 
option to 1.
• In Program 1001 - Loop Length (page 502), 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 372 for compatibility with the connected telco or 
PBX/Centrex.
Step 3: Are connected trunks DTMF or Dial Pulse (DP)?
• In Program 0402 - Manual DTMF Tone On 
(page 462), set the DTMF on duration for com-
patibility with the connected telco or PBX.
•Program 0402 - Manual DTMF Tone Off 
(page 462), se the DTMF off duration for compat-
ibility with the connected telco or PBX.
• In Program 0402 - DP Make Timer (page 461), 
set the DP make (on) interval for compatibility 
with the connected telco or PBX.
• In Program 0402 - DP Break Timer (page 461), 
set the DP break (off) interval for compatibility 
with the connected telco or PBX.
• In Program 0402 - DP Interdigit Timer 
(page 461), set the DP interdigit (time between 
digits) interval for compatibility with the con-
nected telco or PBX.

Step 4: For Direct Trunk Access, should trunk extension numbers be left at their default set-
ting (e.g., 401-448in DS2000 or 401-406 in DS1000).
• In Program 0504 - Trunk Port Extension Numbers 
(Fixed Slot) (page 476), leave the trunk extension 
numbers at their default settings (401-448 in 
DS2000 or 401-406 in DS1000).
• In Program 0504 - Trunk Port Extension Numbers 
(Fixed Slot) (page 476), change the trunk exten-
sion numbers to meet the site requirements (e.g., 
501-516).
Step 5: Should trunk names be left at their default setting (Trunk 1, Trunk 2 etc.).
• In Program 1001 - Trunk Name (page 498), leave 
the trunk names at their default setting.
• In Program 1001 - Trunk Name (page 498), 
change the trunk names to meet the site require-
ments.
Step 6: Set the trunk access options at each extension for each trunk.
• In Program 1803 - Extension Line Access Assign-
ments (page 546), enter 0 to prevent both incom-
ing and outgoing access on the trunk.
• In Program 1803 - Extension Line Access Assign-
ments (page 546), enter 1 to allow incoming 
access only.

• In Program 1701 - Line Key (page 518), make 
sure no keys are assigned as line keys (code 03).
• In Program 1701 - Switched Loop Key 
(page 517), or in Program 1701 - Fixed Loop Key 
(page 517), assign a loop key to any extension 
without line keys. This allows the extension to 
answer trunk calls.
Step 8: Should DSS Console have line keys for placing trunk calls?
• In Program 1704 - Line Key (page 528), assign 
programmable keys as line keys (code 03). The 
options are 1-48 (for trunks 1-48) in DS2000, 1-6 
in DS1000.
• In Program 1704 - Line Key (page 528), make 
sure no keys are assigned as line keys (code 03).
Step 9: Should extension user have single digit (dial 9) access to outside calls?
• In Program 0501 - Single Digit Access 
(page 475), enter Y.
• In Program 1802 - Station’s Dial 9 Group 
(page 540), assign the Trunk Group (0-8) the sta-
tion will select after the user dials 9.
• In Program 1002 - Trunk Groups (page 506), 
assign trunks to Trunk Groups.
• In Program 0501 - Single Digit Access 
(page 475), enter N. Users dial 9 followed by the 
Trunk Group number (0-8).
• In Program 1002 - Trunk Groups (page 506), 
assign trunks to Trunk Groups (0-8).
Step 10: Should extension have Line Dial-up capability (i.e., the ability to dial #901-#916).
• In Program 1802 - Line Dial Up (page 540), 
Enter Y.

• In Program 0402 - Loop Current Detection Time 
(page 463), set the loop disconnect interval for 
compatibility with the connected telco or PBX.
• In Program 0402 - Loop Current Detection Time 
(page 463), leave this option at its current setting.
Step 14: Do users ever experience call colissions (i.e., connect to an incoming call while 
placing an outgoing call)?
• In Program 0402 - Force Idle (Trunk Guard Time) 
(page 460), lengthen the trunk guard time.
• In Program 0402 - Force Idle (Trunk Guard Time) 
(page 460), leave the trunk guard time at its cur-
rent setting.
Step 15: If the system encounters a defective trunk while placing a call, does it wait the 
proper interval before automatically cycling to the next trunk?
• In Program 0402 - Line Response (page 459), 
leave this interval at its current setting.
• In Program 0402 - Line Response (page 459), set 
the Line Response interval to meet the site’s 
requirements.

DS1000/2000 Software ManualChapter 1: Features99
Programming List
Program 0402 - Line Response (page 459)
When the system fails to detect loop current on a trunk, it will wait this interval before mark-
ing the trunk as defective. Be sure the value you enter is compatible with the local telco.
Program 0402 - Force Idle (Trunk Guard Time) (page 460)
Set the guard time for trunks. When the system disconnects a trunk (e.g., after a user hang up), 
the system keeps the line idle until this timer expires. The Trunk Guard Time helps prevent 
call collisions.
Program 0402 - DP Make Timer (page 461)
Set the duration of the Dial Pulse Make signal (i.e., relay closed). This is the “on” time in a 
Dial Pulse digit. Set this timer for compatability with the connected telco or PBX/Centrex. 
Keep in mind that there are three components of a Dial Pulse digit: Make interval, Break 
interval and Interdigit interval.
Program 0402 - DP Break Timer (page 461)
Use this timer to set the duration of the Dial Pulse Break signal (i.e., relay open). This is the 
“off” time in a Dial Pulse digit. Set this timer for compatability with the connected telco or 
PBX/Centrex.
Program 0402 - DP Interdigit Timer (page 461)
Set the duration of the Dial Pulse Interdigit signal (i.e., relay open time between each digit). 
Set this timer for compatability with the connected telco or PBX/Centrex.
Program 0402 - Manual DTMF Tone On (page 462)
Set the duration of DTMF digits for trunk calls manually dialed by an extension user. This is 
required because the system buffers the digits the user dials. Set this timer for compatibility 
with the connected telco or PBX/Centrex.
Program 0402 - Manual DTMF Tone Off (page 462)
Set the duration of the interval between DTMF digits for trunk calls manually dialed by an 
extension user. This is required because the system buffers the digits the user dials. Set this 
timer for compatibility with the connected telco or PBX/Centrex.
Program 0402 - Loop Current Detection Time (page 463)
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 - Codec Digitizing Method (page 463)
Be sure this option is always set to 0 (
µ-law companding enabled).  Do not set this option to 
1 (A-law companding enabled).
Program 0501 - Numbering Plan (page 472)
Review this option when if you want to change the digits user’s dial for Direct Trunk Access 
(normally 4 followed by the trunk number).
Program 0501 - Single Digit Access (page 475)
Use this option to enable or disable single digit access. If enabled (Y), users can dial 9 to 
select their assigned dial 9 Trunk Group. If disabled, users must dial 9 followed by the Trunk 
Group number (0-8 for Trunk Groups 0-8).
Program 1001 - Trunk Circuit Type (page 498)
Set the trunk’s circuit type for compatiblity 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).• In Program 0501 - Numbering Plan (page 472), 
set up another digit (in place of 4) that meets the 
site’s requirements. Step-by-step guide for setting up Central 
Office Calls, Placing (Page 5 of 5)

Program 1001 - Trunk Name (page 498)
Assign extension numbers and names to trunk ports.
Program 1001 - Trunk Transmit Gain (page 499)
Set the trunk’s transmit gain (0-60) to compensate for the transmit gain characteristics of the 
connected telco or PBX.
Program 1001 - Trunk Receive Gain (page 501)
Set the trunk’s receive gain (0-60) to compensate for the receive gain characteristics of the 
connected telco or PBX.
Program 1001 - Loop Length (page 502)
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.
Program 1002 - Trunk Groups (page 506)
Assign trunk Trunk Groups (0-8).
Program 1701 -  Line Key (page 518)

trunk access codes (#901-#948 in DS2000, #901-#906 in D1000).
Program 1802 - Station’s Dial 9 Group (page 540)
Assign the trunk group (0-8) a user accesses when they dial 9 for an outside line or press a 
switched loop key. This option does not apply to systems with ARS installed.
Program 1802 - Key Access to Outbound Lines (page 541)
Enter Y to enable an extension user to press a Programmable Function Key to access and out-
side line.
Program 1803 - Extension Line Access Assignments (page 546)
For each extension, assign the access options for each trunk (0 = No access, 1 = Incoming 
only. 2 = Outgoing only, 3 = Full access).
Program 1804 - Trunk Group Access (page 549)
For each extension, enter Y to allow or N to prevent outgoing trunk group access. The system 
always allows incoming trunk group access.
