Trunk Support - Tl 
Description Ti trunks are supported using Ti/D4 channel associated signaling (CAS), 
also referred to as DS-I . 
Tl trunk cards support DID, tie, CO and DISA operation on a per circuit 
basis. For each circuit, the circuit descriptor can be programmed through 
CDE to alter the signaling scheme to one of E&M, DID loop-tie, CO (loop 
and ground start), DISA E&M, DISA DID loop-tie, DISA CO (loop or ground 
start). 
The PABX provides for a Stratum 3 or 4 clock source. The PABX can be 
used in master mode to serve as a clock source for the network, or in slave 
mode to use the network as its clock source. In slave mode the system 
prevents data losses due to clock rate differences by adjusting its internal 
Tl clock module to remain in phase with the incoming frame clock rate. 
Tl Trunk Maintenance 
The PABX automatically monitors various errors on a link and maintains a 
24-hour sliding window for each link. Thresholds are programmable on a 
link basis for these errors. When the thresholds are exceeded, based upon 
the threshold type (maintenance, service, or network synchronization), the 
PABX generates maintenance logs, removes the link from service, or 
causes the link to not be used as a network synchronization source. Once 
the link is removed from service or is removed from network 
synchronization, a programmable timer starts. When this time is elapsed, 
if the link does not exceed a specified number of errors, the link is again 
made available for use. All of this activity is logged in maintenance and the 
cumulative error counts (24-hour basis) are available in maintenance error 
reports (refer to the RS-232 AIainrenance ~errnina/ f r&ice). 
There are two different states for a Tl trunk that is out of service, a yellow 
or red alarm. A yellow alarm is the result of a link-based event. The link 
transmits a yellow alarm condition on the link, which signals the far end that 
the link is out of service. This is the action taken on the service threshold 
limits or the reception of a yellow alarm condition from the far end. 
A red alarm is based upon loss of synchronization on the link. Maintenance 
logs are generated for any change in alarm status, and can be seen by 
using the maintenance SHOW STATUS command. 
A link monitoring tool is available for troubleshooting Tl links, and for 
specifying a manual network synchronization source. Refer to the, i%-232 
Maintenance Terminal Practice. 
Tl Trunk Synchronization 
The PABX provides for Stratum 3 or 4 clock source, and can be used in 
master or slave mode. There is a programmable list of links to be used in 
network synchronization, with each link backing up the other links, should

							Features Description 
the previous link exceed the error thresholds (Slip Rates, Bit Error Rates 
(BER), and Framing Losses) programmed in the linkdescriptors. There are 
three network synchronization modes in the PABX: Auto, Manual, and 
Freerun. Auto mode is when the PABX chooses the network 
synchronization source automatically. Manual mode is when a link is 
specifically selected as the network synchronization source (this only lasts 
for 24 hours, at which point the system reverts to auto or freerun mode). 
Freerun mode is when there is no clock source or no link to be used as a 
network synchronization source. The PABX changes modes based on user 
actions, thresholds, and events on the Tl links. Maintenance logs notify 
the installer of these changes. 
Conditions The following conditions apply to this feature: 
l There are 12 link descriptors available. 
l There can be up to 8 network synchronization sources for network 
synchronization. 
l One link provides 24 trunks. 
l If a link descriptor is not assigned (it is recommended that one is 
assigned) then the default values in the link descriptors will apply. A 
link cannot be a network synchronization source without a link 
descriptor. 
l If the last available network synchronization source specified is 
removed from service then the PABX is put into free-run mode. 
l When a network source link is returned to service or is again ready for 
use as a network synchronization source, then the system will review 
the list of network synchronization sources and possibly select the 
returned link (depending upon the current network synchronization 
source and the order of the links in the list). 
l A link is removed from service immediately, regardless of activity on 
the link, when its service threshold limits are exceeded. 
l The Ti Link Monitor feature is not available in maintenance until at least 
one circuit is programmed (CDE forms 14 or 15) on a link in the PABX. 
l The Tl Clock Module clock rate is adjusted by the system if there are 
entries made in CDE Form 44 (Network Synchronization) and one of 
the links there is available. If no network synchronization source is 
available, then the clock rate will not be adjusted by the PABX. 
l The threshold error counts are cleared when the Tl card is plugged in 
or any of the values in the link descriptor assigned to the link are 
changed in CDE Form 42 (Tl Link Descriptors). A change in link status 
has no effect. 
l Changing the entries in CDE Form 44 (Tl Network Synchronization) 
will override manual mode and change the PABX mode to freerun or 
auto. 
l The term link is synonymous with a Tl trunk card. 
l The normal maintenance busy-out feature applies to a circuit on a link 
and not the link itself. The link remains active but the circuit(s) are 
disabled.

Operation None. 
Uniform Call Distribution (UCD) 
Description 
Uniform Call Distribution (UCD) concentrates incoming trunk traffic onto 
one or more special agent hunt groups. Trained operators (agents) answer 
the calls. If all agents are busy, the caller camps on and may be connected 
to a recording hunt group, where the caller hears recorded announcements. 
The caller retains his position in the queue. If the agents are still busy when 
the recording ends, the system connects the call to Music-on-Hold (if 
provided). After a pre-determined time, the unanswered call is rerouted to 
a designated answering point. 
The call rings an agent immediately when one is available. 
Agents can log in and out of the agent hunt group to control the arrival of 
calls from the agent hunt group. 
When a caller is connected to a Recorded Announcement Device (RAD), 
full two-way audio is provided. This allows the caller to leave a message 
with the RAD device (if desired), while waiting for the UCD group. 
See RAD Suppoti for details on recording devices. 
For night service handling, trunk calls can be routed to a recording device 
directly; see intercept To /?ecorded Announcement. 
Conditions The following conditions apply to this feature: 
l If there is no hold timeout point and recordings are given, then for loop 
start trunks that do not provide release supervision, the system does 
not disconnect the trunk; the trunk remains on Music-on-Hold. It is

2-304 important to provide a routing point for these unanswered calls to ensure 
that the loop start trunk is either answered, or timed out for no answer 
and then released. 
Agent hunt groups are special hunt groups; hunt group conditions plus 
some additional features apply to them. 
Circular hunting is advised for the agent hunt group to distribute the 
calls in the group. There is no distribution of calls based on workload 
or waiting time; see Automatic Call Distribution (ACD). 
Campon to agent hunt groups follows the normal campon to hunt 
groups. The recording and reroute features are available once a caller 
has camped on to the agent hunt group. 
Features available for hunt groups, such as Trunk Campon Warning 
Tone and Swap Campon, are available to agent hunt groups. 
The recording hunt group is selected from the tenant of the first 
programmed member of the hunt group. 
If there is no recording programmed, then no music is provided; it is 
only provided after the recording. 
The system provides a recording for the caller as soon as a recording 
device is available. 
At least one hunt of the agent hunt group is done before the waiting 
timeout timer is started (regardless of the waiting timeout length). 
If the waiting timeout time is set to 0 seconds then the timeout effectively 
is an overflow busy point for the agent hunt group. 
A reroute is done for the waiting timeout. 
If the caller is listening to a recording at the time of the waiting timeout, 
the recording is terminated before the reroute is done. If the waiting 
timeout occurs while listening to music and if a campon is done on the 
reroute point then music is maintained while waiting for the busy reroute 
point. Otherwise it is removed and normal call progress tones provided. 
The waiting timeout is ignored if the caller is ringing an agent at the time. 
If the waiting timeout occurs while ringing a recording device then the 
ringing recording device stops ringing and the caller is rerouted to the 
timeout point. 
By default all agents are logged into an agent hunt group. 
Logging out of an agent hunt group only prevents calls from being 
presented to the agent set from the agent hunt group. Other features 
are not affected. 
An agent that is logged out will not be selected to receive campon beeps 
and the swap campon capability for the hunt group; see Swap Campon 
And Campon Warning Tone. 
When an agent becomes available and is rung by a waiting caller, the 
recording or music is removed and the caller hears ringback tone. 
UCD agent hunt groups and ACD agent groups are completely separate 
and different entities. The first is a collection of devices, and the second 
is a collection of agent id codes. 
The campon warning tone can be turned off for members of the agent 
hunt group; see Campon Warning Tone. Issue 1 Revision 0 March 1997

Voice Mail - ONS Port 
Description 
This feature integrates an SX-2U0 PABX with an ONS Voice Mail system. 
The integration is based on the use of system abbreviated dial numbers. 
This eliminates several dialing steps involved in the sending and retrieving 
of voice mail messages. 
Special codes allow the PABX operation to be customized to suit the 
operation of the particular voice mail system. Refer to the programming 
instructions for Form 31 - System Abbreviated Dial Entry, for a description 
of these special codes. 
Conditions The following conditions apply to this feature: 
l This feature does not conflict with the Voice A&i/ - COVF’oHfeature - 
both systems may be installed simultaneously. 
l This feature does not conflict with other ONS voice mail systems - they 
may be installed simultaneously. 
l The *I, *6, *9, codes are only operational with the ONS Voice Mail 
feature. If the abbreviated dial number dials anything but an ONS voice 
mail hunt group, the codes are ignored. 
l The *4 and *8 codes are used with the M/TEL MA/L Enhanced lnband 
Signaling. 
l Callers hear ringback while the digits are pulsed to the voice mail 
system. Audio is not cut through until after the last pause has been 
executed.
