							Features Description 
Trunk Intercepts- 
Description 
DID and DISA calls to no answer, busy, DND, vacant, invalid or 
DID-restricted extensions can be rerouted to the console, another 
extension, a hunt group, the ring group or the Night Bell. There are two 
intercept points for each Inward Dial trunk, one for Day Service and the 
other for Night Service. 
Conditions 
l If there is no Illegal Number Intercept Point or it is busy, DID trunks 
calling vacant, invalid or DID-restricted extensions will receive reorder 
tone. 
l If the intercept point is busy and the Camp On feature is enabled, the 
DID or DISA trunk camps on to the intercept point. 
l Calls cannot be forwarded from an intercept point. 
l If a DID or DISA trunk calls a busy station that has both the Call 
Forward on Busy and the Busy Intercept features enabled, the trunk is 
routed to the Call Forward on Busy destination. 
l If a DID or DISA trunk calls a station that has Call Forwarding -Always 
programmed, the call follows the Call Forwarding programmed at the 
station. 
l When a DID or DISA trunk routes to a station that is busy, and Busy 
Intercept is enabled, the trunk is rerouted to the intercept point. If Busy 
Intercept is disabled, busy tone is returned. 
l When a DID or DISA trunk routes to a station that has Do Not Disturb 
set, and Do Not Disturb Intercept is enabled, the trunk is rerouted to 
the intercept point. If Do Not Disturb Intercept is disabled, busy tone is 
returned. 
l If a DID or DISA trunk routes to a station that has the No Answer 
Intercept, the Call Forward No Answer timer for the destination station 
begins timing. Once the timer expires, the trunk routes the call to the 
intercept point. If the station has Call Forward No Answer enabled, the 
No Answer Intercept has no effect. If No Answer Intercept and Call 
Forward are disabled, the trunk continues to ring the station. 
l When a DID or DISA trunk dials an invalid number, and Illegal/Vacant 
Number Intercept is enabled, the call routes to the intercept point. 
l If an intercept point answers a call, Answer Supervision is sent out on 
the trunk. 
l The day and night answer points (Commands 501 - 580, Register 4 
and 5) which specify where non inward dial trunks are to ring, will be 
interpreted as intercept points for inward dial trunks. 
l Call Fomarding - Busy and Call Forwarding - No Answer override the 
Busy/No Answer Intercept feature.

							Features 
Trunk Signaling - DTMF Or Rotary Outpulsing 
Description 
This feature automatically converts DTMF signals to dial pulse (rotary) 
signals where the CO trunk is not equipped to accept DTMF signals. It 
also converts dial pulses from rotary station sets to DTMF for DTMF 
trunks. 
A user can dial #to force all digits that follow to be sent as DTMF, regardless 
of the trunk type. 
Conditions If DTMF or Rotary Outpulsing (field g) has been set to 1, (Rotary), both 
DTMF signals and rotary pulses are sent out on the trunk, as early line 
split is not provided. Where this double signaling can cause difficulties in 
digit detection, (field g) should be set to 2 (Rotary, Disable Outgoing 
Audio Until Answer). If the trunk does not supply answer supervision, 
transmit audio is enabled. 
l 10 seconds after the last digit has been dialed 
OR 
l immediately, if the number is followed by the digit #. 
If DTMF or Rotary Outpulsing (field g) has been set to 2, the following must 
also be programmed in Trunk Group Programming (Commands 151 - 156), 
Register 2: 
l Answer Supervision (field e) must be set to 1 (Supervision is Meter 
Pulse or Reversal). Default is 0 (No Supervision). 
The # digit can be embedded in a Speed Call, or in an ARS Digit Modification 
Table Entry. 
Tone to Pulse Override can only be used from SUPERSET telephones, 
DTMF sets and from the Attendant Console. 
Programming Command 100, System Options, Register IO, Features Selection 2: 
l Set Use of Hash (#) For Trunks (field f) to 0 (Enable tone to pulse 
override) or 1 (Enable end of dial). The default is 0. 
Commands 151 - 156, Trunk Groups 1 + 6 Programming, Register 2: 
l DTMF or Rotary Outpulsing (field g) must be set to 1 (Rotary), 2 
(Rotary, Disable Outgoing Audio Until Answer) or 3 (Rotary, Inhibit 
DTMF Until Answer). Default is 0 (DTMF). 
Operation None.

							Features Descrbtion 
Trunk-To-Trunk-Plus Station Conferencing 
Description 
This feature permits an extension user (involved in an established trunk 
call), to place the trunk on Consultation Hold and access a second trunk. 
The user can then converse privately withthe third party or form a 
3-party conference. 
If the user hangs up and has “Authorized Trunk to Trunk Connection” 
capability enabled in his/her Class of Service, the two trunks can continue 
the conversation; otherwise, the two trunks are disconnected. With 
Authorized Trunk to Trunk Connection capability enabled, the extension 
user is also able to transfer (supervised or unsupervised), a trunk call to 
another trunk call. 
Conditions l The system supports a maximum of six 3-party conferences. 
l The appropriate types of trunk interconnection must be enabled in 
System Options, Command 100, Register 5. 
l The CO must provide Disconnect Supervision and Disconnect 
Supervision Guaranteed? (field c) must be set to 1 (Yes). Default is 0 
(No). 
l Authorized Trunk to Trunk Connection must be enabled in the 
extension user’s COS in order for two trunks to continue a conference 
once the extension user hangs up. 
l Authorized Trunk to Trunk Connection must be enabled in order for an 
extension user to transfer a trunk call to another trunk call. 
Programming Command ‘100, System Options, Register 05, Trunk Connections: 
l Enable the following types of trunk interconnection, as required. In all 
cases, the default is 0 (Disable). 1 is Enable. 
CO-to-CO is field c 
E&M-to-E&M is field d 
CO-to-E&M is field e 
DID-to-CO is field g 
DID-to-E&M is field h 
DID-to-DID is field i 
l If a warning tone is required, set Conference Warning Tone (field 9 to 
1 (Enable). Default is 0. This applies to CO Trunks only. 
Commands 121 -+ 129, Class of Service Programming, Register 1: 
l Set Authorized Trunk to Trunk Connection (field j) to 0 (Disable) or 1 
(Enable). Default is 1.

Features Description 
Unlimited Wait For Dial Tone 
Description 
This feature permits interconnection to extremely slow Central Offices 
(i.e., dial tone delays of 30 minutes). This feature seizes a trunk and 
holds it for an indefinite period. Upon the receipt of dial tone, the 
extension can outpulse the digits. 
Conditions l In most cases, the system Dial Tone Detectors CAN detect the dial 
tone provided by the Central Office. For these cases, Wait ForDial 
Tone must be set to 2 (Check for Dial Tone every 5 Seconds). Once 
dial tone is heard, a DTMF Receiver connects to the trunk. Once the 
detector detects the dial tone, outpulsing can begin. This condition en- 
sures the correct operation of Toll Control. 
l In some cases, the system Dial Tone Detectors CANNOT detect the 
dial tone provided by the Central Office. For these cases, Wait For Dial 
Tone must be set to 3 (Unlimited Wait, With Detection by User). Once 
dial tone is heard and the switchhook is flashed (SUPERSET 
telephones must dial the digit I), a DTMF Receiver connects to the 
trunk. Outpulsing can begin immediately. 
Programming Commands 151 - 156, Trunk Groups l.- 6 Programming, Register 2: 
l Wait for Dial Tone (field b) must be set to 2 (Check for Dial Tone Every 
5 Seconds) or 3 (Unlimited Wait With Detection by User). Default is 0 
(No Wait). 
Operation When Wait For Dial Tone is Set to 2: 
Go off-hook at an extension. 
Dial the Trunk Group Access Code. 
The Dial Tone Detector checks for dial tone. 
If no dial tone is detected after 5 seconds, then the Dial Tone Detector 
and DTMF Receiver are removed. 
The system then waits 5 seconds before connecting the Dial Tone 
Detector to check again for dial tone. 
The Dial Tone Detector is connected for 1.5 seconds to check for dial 
tone. 
If there is still no dial tone, then the system removes the Dial Tone 
Detector for another 5 seconds. 
This process of connecting the Dial Tone Detector 5 seconds OFF, 1.5 
seconds ON intervals is continued until the system detects dial tone. 
At this time, the DTMF Receiver is connected.

							Features 
When Wait For Dial Tone is Set to 3: 
l Go off-hook at an extension. 
l Dial a Trunk Group Access Code. 
l Dialed digits are not outpulsed but the trunk and Dial Tone Detector 
remain seized. 
l When dial tone is heard, flash the switchhook (SUPERSET telephones 
must dial the digit 1). The DTMF Receiver is assigned to the trunk 
which allows dialed digits to be outpulsed normally.
