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.
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.
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.
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.

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.
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 1321 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.
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).
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.

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.
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). 
Valid entries Usage

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 
y for DS1 circuit packs that serve as primary or secondary 
synchronization references. 
Near-end CSU Type
This field appears only when the DS1 circuit pack is a TN767D or TN464E or 
later suffix model, the Bit Rate field is 
1.544 and the Country Protocol field is 1 
(U.S.). This field does not display for all circuit packs.
Valid entries Usage
y
Enter y to allow maintenance software to measure the slip-rate 
of this circuit pack and determine whether it’s excessive. 
Typically, enter 
y for DS1 spans used for data applications and 
for spans used as synchronization references. This excludes all 
T1-spans connecting channel banks, unless the channel bank is 
externally timed. This entry enables switching between the 
primary and secondary synchronization references and an 
internal high-accuracy clock.
n Enter n for DMI-BOS links or when testing is not required. 
Normally, enter 
n for DS1 spans that are used exclusively for 
voice and that do not serve as the primary or secondary 
synchronization source.
Valid entries Usage
other
Enter other if no channel service unit is attached to the DS1 
facility or if the CSU is an external unit. No options are 
available on page 2 for administering an external CSU.
integratedEnter integrated if a 120A CSU module is attached to the DS1 
board. This integrated channel service unit (ICSU) can accept 
software-administrable option downlinks (that is, it can respond 
to test codes from technician’s equipment and report its status). 
When you enter 
integrated, fields for administering options on 
the ICSU appear on page 2 of the DS1 Circuit Pack screen.

Send ANSI-T1.403 One-Second Performance 
Reports
This field selects whether your DS1 circuit pack will send error reports to the 
far-end switch. These reports are useful for network management, and are sent at 
1-second intervals when enabled. This field appears only if the Framing Mode 
field is 
esf. It is used only with circuit packs that have an integrated channel 
service unit (CSU).
Far-end CSU Address
This field, which, appears only if the Framing Mode field is 
esf.
Transmit LBO (Transmit Line Build-Out)
This field reduces the outgoing signal strength by a fixed amount. The appropriate 
level of loss depends on the distance between your switch (measured by cable 
length from the smart jack) and the nearest repeater. Where another switch is at 
the end of the circuit, as in campus environments, use the cable length between the 
2 switches to select the appropriate setting from the table below. This field appears 
if the Near-end CSU Type field is 
integrated.

compensate for line losses. 
Upon DTE LOS
DTE stands for “Data Terminal Equipment.” This field tells the switch what to do 
if the outgoing signal from the DS1 circuit pack (the data terminal equipment) to 
the network is lost.
Supply CPE Loopback Jack Power
If a CPE (Customer Premise Equipment) Loopback Jack is installed, the DS1 
board should supply power to the equipment during loopback testing.
