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...

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...

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...

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...

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...

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...

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...

DCP/ANALOG Bearer Capability
This field appears when the Signaling Mode field is 
isdn-pri. It is used to 
determine bearer capability encoding.
MMI Cabling Board
This field appears only if the MMCH field is 
y on the System-Parameters 
Customer-Options screen.

Received Digital Metering Pulse Maximum (ms)
This field appears only when the Signal Mode field is 
cas (Channel Associated 
Signaling), the Interconnect field is 
co or pbx, and the Country Protocol field is 
administered for a protocol that uses periodic pulse metering (PPM) as defined in 
Table 11 on page 625
. The default value depends on the Country Protocol field’s 
entry....

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...
