C. Tl PROGRAMMING 
13.56 The 
Tl Programming window allows you to 
program information that applies to all Tl trunks as well 
as to specific Tl Cards. The information that is pro- 
grammed 
common to all Tl Cards includes: 
l Ermr thresholds: The programmer can set numeri- 
cal thresholds (number per 
hour and number per 
day) forT1 Card errors. 
If a threshold is exceeded, an 
error is printed on the SMDR report. (These are set to 
default values that, in most cases, will not need to be 
changed.) Possible Tl errors include the following: 
- 
BPV (Bipolar Violations): This is a non-zero sig- 
nal element that has the same polarity as the pre- 
viously received non-zero element. 
- 
Controlled Slips: The 416/832 System replicated 
or deleted one 192-bit digital signal (DSl) frame 
due to a lack of frequency synchronization. 
- 
CRC-6 (Cyclic Redundancy Check): The cal- 
culation carried out on a set of transmitted bits by 
the transmitter does not match the calculation 
performed by the 416f832 System. 
- ES (Errored Seconds): These are seconds in 
which at least one error occurred. 
- 
OOF/COFA (Out of Frame/Change of Frame 
Adjustment): OOF is a state in which the frame 
alignment that is received is not consistent with 
that which is transmitted. COFA occurs when the 
416/832 System realigns its receiver to the prop 
er frame alignment signal. 
- 
SES (Severely Errored Seconds): This is a 
second during which transmission performance 
is degraded below an acceptable level. 
- TODV (Transmit Ones Density Violations): If 
there are too few ones in a transmission (low den- 
sity of pulses representing ones), the excessively 
long string of zeros causes a pulse density error. 
This condition is monitored only when the on- 
board CSU is enabled. 
- 
UAS (Unavailable Seconds): This is the time in- 
terval during which the Tl span is unavailable 
for service. This time begins with 10 or more 
consecutive Severely Errored Seconds and ends 
with 10 or more Non-Severely Errored Seconds. 
0 
Dialing feedbackconfiguration: When a number is 
dialed over a Tl circuit, the user hears the feedback 
from the signals (either DTMF or dial-pulse). By ad- 
justing the M’MF gain control or the dial-pulse gain 
control, you can determine how loud the signals ap- 
0 
Page 5-122 pear to the user. If the circuit is designated for dial- 
pulse signaling, you can also select the type of dial- 
pulse tone the user hears (23 different tones are 
available). 
Reference clock back-up priorities: One Tl Card 
in the system must be programmed 
as the system ref- 
erence clock. 
If more than one Tl Card is installed in 
the system, the programmer may designate one or 
more of the cards as a “backup” to the system refer- 
ence clock. Then, if the Tl Card acting as the system 
reference clock fails or is taken out of service, the 
next Tl Card on the back-up priority list takes over. 
If no backups are assigned or all Tl cards fail, the 
Matrix Card clock acts as the backup. 
1357 The information that is programmed specific to 
each Tl Cad 
installed in the system includes the fol- 
lowing. This information is determined by the equip- 
ment being used. Refer to the chart on the next page for 
programming requirements and refer to INSTfiA- 
TION for special cabling requirements. 
Card type: The type of framing scheme used by the 
Tl trunks connected to the card can be D4 Super- 
frame or Extended Superframe @SF). 
Zero code suppression scheme: The Tl trunk zero- 
suppression scheme for the trunks on the Tl card can 
be AMI (Bit 7), Bipolar Eight Zero Substitution 
@=% or Unone.n 
PCM encoding law: In pulse code modulation 
(PCW systems, there are two primary methods of 
encoding analog signals (sampled audio wave- 
forms) into digital signals. In North America and Ja- 
pan, the “mu-law” (p-law) method is normally used. 
In other places, such as Europe, the “A-law” method 
is 
widely used. The programmer must select both the 
transmit and receive method of encoding used by the 
TlC. In the United States, this will almost always be 
mu-law to mu-law. 
Relay activation: If desired, you can enable one or 
both of the two relays on theT1 Card. 
If enabled, you 
can attach a signaling device (such as a light or 
alarm) and select whether the relay is in “set” mode 
for a “Tl line error” (red alarm) or to indicate “Tl 
line OK” 
Channel service unit (CSU) or DSX-1 Interface: 
Designate whether the optional on-board CSU is in- 
stalled on the Tl Card or if a DSX-1 Interface will be 
used. Also verify that the DSXKSU jumper on the 
Tl Card is set in the proper position (to match data- 
base programming.) Then program one of the fol- 
lowing:  
						

							INTER-TELPRACTICES PROGRAMMING 
IMX/GMX 416/832 INSTALLATION & -ANCE Issue 1, November 1994 
- Line build-out (LBO): 
If the optional on-board 
CSU is installed, designate the LB0 attenuation 
of the Tl trunk connected to the card. This value 
is determined by the distance to the nearest pub- 
lic network Tl repeater. 
- 
DSX-1 line length: If the optional on-board 
CSU is 
not installed, designate the length of the 
cabling between the Tl Card and the external 
CSU, or between the Tl Card and the other tele- 
phone system. 
NOTE: The programming prompts for LB0 attenu- 
ation and DSX-1 line length assume that proper Tl 
cable is being used. When transmitting over shorter 
distances (e.g., when the nearest public network Tl 
repeater is less than 2000 feet from the MDF), it may 
be possible to use standard two-pair voice frequency 
cable instead; however, you may have to compen- 
sate by selecting longer LB0 distances or DSX-1 
line lengths. Also, no matter which type of cable is 
used, the transmit and receive pairs must be shielded 
from each other (or run in separate cables or binder 
groups)- 
Reference clock programming: First determine 
whether the Tl Card is connected to the public net- work. If it is, the card is automatically designated as 
a slave clock (the public network always acts as the 
master clock and the first slave clock provides the 
system reference clock; all other slave clocks act as 
backups). If the card is not connected to the public 
network, but is connected to another Tl Card or a 
card in another telephone system, determine wheth- 
er the card is a master clock or a slave clock (in rela- 
tion to the card on the other end). 
l Error diagnostics: If desired, you can generate a re- 
port that shows the current Tl error counts (by hour 
and by day) for the selected card. The error counts 
can be displayed in a graph or a table. 
13.58 There are Tl services available that function 
like a DID trunk for incoming calls and an F&M trunk 
for outgoing calls. For an outgoing call, the trunk direct- 
ly accesses another PBX and allows the usual F&M 
calls to be placed. For incoming DID-type calls, the Tl 
trunk receives the incoming call and then waits for 2-4 
additional digits to be dialed. These digits must corre- 
spond to the digits in a DID table so that the 416/832 
System will know where to send the call. (The DID digit 
translation tables are programmed in the DID Group 
window shown on page 5-115.)

Tl APPLICATIONS AND PROGRAMMING 
NOTE: For all installations, the card type and zero code are programmed to match the Tl span being installed. The 
PCM encoding law is determined by the location in which the Tl span is installed; in the United States it will usually 
be 
“p-law to p-law.” For the line build-out or line length option, select the number closest to the actual installation dis- 
tance. If a TlC is a Master, the source of the reference clock will always be “on-board oscillator” (“external 
clock” is 
reserved for future use). Refer to page 2-22 in SPECE’ICATIONS for more information.
