Line Compensation
The appropriate entry in this field varies with the type of cable used, so work with 
your network service provider to determine the correct setting in your situation. 
The following table shows the appropriate entries for different lengths of 
22-gauge ABAM cable terminated on a DSX-1 cross-connect.
The following table shows the appropriate entries for different lengths of 
22-gauge ABAM cable directly connecting to DS1 interfaces.
Framing Mode
Use this field to select either superframe (sf or d4) or extended superframe (esf) 
for T1 service on the DS1 link. The framing mode you use must match the mode 
used on the other end of the link, so work with your network services provider to 
determine the appropriate entry for this field. 
This field only appears if the Bit Rate field is 1.544 (that is, if you’re using T-1 
service). If you’re using E-1 service, DEFINITY ECS automatically selects 
CEPT1 framing.
Tip:
Lucent recommends using ESF when your service provider supports it, 
especially if you may someday upgrade the facility to ISDN. The ESF format 
provides enhanced performance measurements and uses a sophisticated 
error-checking method to ensure data integrity.

Signaling Mode
This field selects the signaling method used for the DS1 link. This mode must 
match the method used on the other end of the link, so work with your network 
services provider to determine the appropriate entry for this field.
D-Channel
The Japanese 2Mbit trunk circuit pack, when administered to support ISDN-PRI 
signaling, allows you to assign the D-channel to any channel from 1 to 31 in an 
E-1 facility. You cannot submit the screen if this field is blank. Using the 
change 
ds1
 command, you can change this field if the D-channel is not used in a 
signaling group. This field appears only when the Location field indicates the 
circuit pack is a Japanese 2Mbit trunk circuit pack and the Signaling Mode field is 
isdn-pri.
Valid entries Usage
d4
Enter d4 to use the basic DS1 superframe (sf). This mode is 
recommended only for voice traffic.
esf Enter esf to use the Extended Superframe format. This mode is 
recommended for digital data traffic. If you enter 
esf for a 
TN464F, TN767E, or a later suffix DS1 circuit pack, a second 
page of the DS1 Circuit Pack screen becomes available to 
administer ESF Data Link options.
Valid entries Usage
CAS
 (Channel 
Associated 
Signaling)Enter CAS for out-of band signaling with E-1 service. This 
setting yields 30 64-kbps B-channels for voice or data 
transmission. Channel 0 is used for framing while channel 16 
carries signaling.
robbed-bitEnter robbed-bit for in-band signaling with T-1 service. This 
setting yields 24 56-kbps B-channels for voice transmission.
isdn-priEnter isdn-pri for either T-1 or E-1 ISDN service. This setting 
supports both Facility Associated Signaling and Non-Facility 
Associated Signaling.
isdn-extEnter isdn-ext for either T-1 or E-1 ISDN service. This setting 
supports only Non-Facility Associated Signaling.
common-chan Enter common-chan, for out-of-band signaling with T-1 
service. This setting yields 23 64-kbps B-channels for voice or 
data transmission. Channel 24 is used for signaling. 
Valid entries Usage

Connect
In order to control communications at layers 2 and 3 of the ISDN-PRI protocol, 
use this field to specify what is on the far end of this DS1 link. This field only 
appears when the Signaling Mode field is 
isdn-pri.
Interface
This field only appears when the Connect field is 
pbx; that is, when this DS1 link 
is providing an ISDN-PRI connection in a private network. The Interface field 
controls how your switch negotiates glare with the far-end switch. The switches at 
either end of the DS1 link must have complementary settings in this field: if not, 
the D-channel won’t even come up. For example, if the switch at one end of the 
link is administered as 
network, the other must be administered as user. 
Valid entries Usage
pbx
Enter pbx if this DS1 link is connected to another switch in a 
private network. If 
pbx is entered, the Interface field appears.
line-sideEnter line-side when the switch is acting as the network side of 
an ISDN-PRI interface. Use 
line-side to connect to Roll About 
Video equipment.
network Enter network when the DS1 link connects this switch to a 
central office or any other public network switch.
hostEnter host when the DS1 link connects this switch to a 
computer.
Valid entries Usage
Use the following 2 values for private network applications in the U.S.
networkEnter network if your switch overrides the other end when 
glare occurs. If you are connecting your switch to a host 
computer, set this field to 
network.
userEnter user if your switch releases the contested circuit and 
looks for another when glare occurs. If you are connecting your 
switch to a public network, set this field to 
user.
Use the following values for private networks (including QSIG networks) 
outside the U.S. Entering either of these values causes the Peer Protocol and Side 
fields to appear.
peer-masterEnter peer-master if your switch overrides the other end when 
glare occurs.
peer-slave Enter peer-slave if your switch releases the contested circuit 
and looks for another when glare occurs.

Interconnect
For E-1 service using channel-associated signaling, the entry in this field tells 
DEFINITY ECS whether the DS1 circuit pack is using a public or private network 
protocol. The entry in this field must agree with the entry in the Group Type field 
on the Trunk Group screen. This field appears only when the Signaling Mode field 
is 
CAS.
Country Protocol
The entry in this field must match the country protocol used by the far-end switch. 
For connections to a public network, your network service provider can tell you 
which country protocol they are using. 
This field appears if the Signaling Mode field is 
CAS or isdn-pri. For the 
Japanese 2Mbit trunk circuit pack, this is a display-only field if the Signaling 
Mode field is 
CAS.
Peer Protocol
This allows you to administer the peer level protocol that will operate in a  private 
network. This field appears if the Interface field is 
peer-master or peer-slave. To 
enter 
Q-SIG, the Basic Call Setup field on the System-Parameters 
Customer-Options screen must be 
y.
Valid entries Usage
pbx
If pbx is selected, the board operates as a tie trunk circuit pack. 
COIf CO is selected, the board operates as a CO or DID circuit 
pack.
Valid entries Usage
1
 to 25Enter the country protocol used by the central office at which 
this link terminates.
etsiEnter etsi if your network service provider uses the protocol of 
the European Telecommunications Standards Institute (ETSI). 
Enter 
etsi only if the Signaling Mode field is isdn-pri.
Valid entries Usage
Q-SIG
This implements QSIG Network Basic Call.
TTCFor private networking. Requires a Digital Trunk (Japan 2 MB 
TTC) (TN2242) circuit pack.

Interworking Message
This field determines what message the switch sends when an incoming ISDN 
trunk call interworks (is routed over a non-ISDN trunk group).
Side
This field controls how your switch resolves glare at layer 3 over an ISDN-PRI 
link in QSIG private networks. It appears if the Interface field is 
peer-master or 
peer-slave.
The default value of the field changes depending upon which value the Interface 
field contains. 
!CAUTION:
It is critical that administration on this switch correctly pairs with the 
administration of the far-end switch. If the far-end is administered as the b 
side, this field should be set to a regardless of whether the layer 2 
designation is peer-master or peer-slave, and vice versa.
Valid entries Usage
PROGress
Normally select this value. PROGress asks the public network 
to cut through the B-channel and let the caller hear tones such 
as ringback or busy tone provided over the non-ISDN trunk.
ALERTingALERTing causes the public network in many countries to 
play ringback tone to the caller. Select this value only if the 
DS1 is connected to the public network, and it is determined 
that callers hear silence (rather than ringback or busy tone) 
when a call incoming over the DS1 interworks to a non-ISDN 
trunk.
Valid entries Usage
a
Enter a if the Interface field is peer-master (this 
switch overrides the far-end when glare occurs).
bEnter b if the Interface field is peer-slave (this 
switch releases the contested circuit and looks for 
another when glare occurs).

Protocol Version
In countries whose public networks allow multiple layer 3 signaling protocols for 
ISDN-PRI service, this field selects the protocol that matches your network 
service provider’s protocol. Refer to ‘‘
Public network signaling administration for 
ISDN-PRI Layer 3’’ on page 1331 to see which countries support which 
protocols.
This field appears only when:
nThe Signaling Mode field is isdn-pri and the Connect field is network.
nThe Signaling Mode field is isdn-pri, the Connect field is pbx, and the 
Interface field is 
user or network.
!WARNING:
The AT&T Switched Network Protocol does not support restricted displays 
of connected numbers. Therefore, if you administer the 1a 
country-protocol/protocol-version combination on the DS1 screen, you 
cannot set the Send Connected Number field to 
r (restricted) on the 
ISDN-PRI Trunk Group screen, as this causes display problems.
Interface Companding
The entry in this field must match the companding method used by the far-end 
switch. This field does not appear for all DS1 circuit packs.
CRC
This field indicates whether a cyclic redundancy check (CRC) will be performed 
on transmissions that the DS1 circuit pack receives. This field does not display for 
all circuit packs.
Valid entries Usage
a
The entry in this field must match the protocol used by your 
network service provider, so work with your vendor to 
determine the appropriate entry.
b
c
Valid entries Usage
alaw
 Enter alaw for E-1 service.
mulaw Enter mulaw for T-1 service.
Valid entries Usage
y
Enter y when the Signaling Mode field is CAS and the DS1 
link is providing E-1 service.
nEnter n for all other applications.

Idle Code
!CAUTION:
Customers: The entry in the Country Protocol field sets the default idle code. 
Do not change the default without assistance from Lucent or your network 
services provider.
For some circuit packs, this is a display-only field.
Channel Numbering
The ETSI and ISO QSIG specifications require that B-channels on an E1 be 
encoded as 1-30 in the Channel ID IE. Prior to this field, DEFINITY ECS only 
used this scheme for Country Protocols 2a (Australia) and 13a (Germany 1TR6). 
This field appears when the Signaling Mode field is 
isdn-pri, the Bit Rate field is 
2.048, the Connect field is pbx, and the Interface field is peer-master or 
peer-slave.
DMI-BOS
The DMI/BOS protocol is used for high-speed digital communications between a 
host computer and a DEFINITY ECS. With this 24-channel protocol, channels 
1–23 of the DS1 link carry data and channel 24 carries control signaling. 
DMI/BOS has greater capacity than a robbed-bit 24-channel facility. This field 
appears only when the Signaling Mode field is 
common-chan.
Valid entries Usage
any 8-digit 
string of 0’s and 
1’sThis entry sets the signal sent out over idle DS0 channels. The 
string must be compatible with the protocol used by the far-end 
switch.
Valid entries Usage
timeslot
sequential
  If the DEFINITY ECS is connected via QSIG trunks to a 
switch supporting the ETSI QSIG or ISO QSIG specifications, 
this field must be 
sequential.
When the Signaling Mode field is 
isdn-pri and the Bit Rate 
field is 
2.048, but the Channel Numbering field does not 
display because of the setting of other fields, it is set internally 
to 
sequential for 2a (Australia) and 13a (Germany).
Valid entries Usage
y
 Enter y to activate the Digital Multiplexed Interface-Bit 
Oriented Signaling (DMI-BOS) format.
nEnter n to use a Lucent Technologies proprietary format.

Slip Detection
Slips — synchronization errors — slow digital transmissions and can result in 
data loss. The switch maintains a slip-count record for each DS1 interface to 
detect errors and evaluate their severity (the type of alarm). If as many as 50 
percent of those spans administered for slip detection are experiencing slips (with 
respect to the primary), then a decision is made to switch to the secondary.
!CAUTION:
Always enter
