597 Dial Plan Record 
17
NOTE:
It is recommended that you do not administer extensions that begin 
with 
0 if the Uniform Dialing Plan is enabled. In the United States of 
America, 
0 is usually the attendant.
nfac (feature access code) only — a FAC can be any number from 1 to 9 and 
contain up to 4 digits. You can use * or #, but only as a first digit.
It is recommended that a FAC be the last item entered in a row when mixed 
numbering is used. Otherwise, problems may occur when 3-digit FACs and 
4-digit extensions begin with the same first digit and the FAC is an 
abbreviated dialing list access code.
The system requires that FACs for AAR and ARS have the longest length 
for a first digit in the First Digit Table.
nmisc (miscellaneous code) — these codes are used if you want to have 
more than one kind of code start with the same digit and be the same 
length. Misc can have a dialed length of 1, and can have a first digit of 
0 
through 
9. Using misc requires that you also define a Second Digit Table. 
npextension — Is made up of a prefix (first digit) that can be a 0through 9 
(* and # not allowed) and an extension number of up to five digits in length. 
The maximum length of a prefix and extension combination is six digits. 
When a prefixed extension is entered in the dial plan, a TAC cannot be 
entered before the prefixed extension on the same row in the table. If a first 
digit is already assigned as a TAC, a prefixed digit cannot be entered after 
the TAC on the same row in the table. 
The purpose of the prefix is to identify the dial type as an extension. After 
digit collection, the prefix digit is removed from the string of dialed digits. 
The remaining digits (extension number) are then processed. A prefixed 
extension allows the use of extensions numbers with any first digit (the 
extension length must be specified on the table). The prefixed extension 
cannot have the same first digit as the ARS or AAR facility access code 
(FAC).
NOTE:
When a dial plan has mixed station numbering, extensions of various 
lengths (all with the same first digit) are mapped on the First Digit 
table as shown on Field descriptions for page 1. The system then 
employs an inter-digit time-out to ensure that all dialed digits are 
collected. The inter-digit time-out may add several seconds to the dial 
time. An alternative to the delay required in the time-out mechanism 
at the expense of dialing an extra digit is to use prefixed extensions in 
the dial plan.

Screen 75. DS1 Circuit Pack screen for Channel Associated Signaling 
Location
This display-only field shows the port address specified in the 
add command 
when the circuit pack was first administered.
Name
Use this field to assign a significant, descriptive name to the DS1 link. Lucent 
recommends putting the vendor’s circuit ID for the link in this field, because that 
information helps you troubleshoot problems with the link, but you could also use 
this field to indicate the function or the destination of this DS1 facility. In that 
case, put the DS1 link circuit ID in the Name field of the trunk group associated 
with this link.
Bit Rate
Use this field to select the maximum transmission rate for DS1 circuit packs that 
support either T-1 or E-1 service. For circuit packs that only support one of these 
services, the field is a display-only field.
NOTE:
Once an add ds1 operation is complete (that is, the DS1 screen has been 
submitted) you can’t change the Bit Rate field with a 
change ds1 
command. Instead, execute a 
remove ds1 command. Then use the add ds1 
command to administer the circuit pack again. You’ll have to re-enter all the 
information for the circuit pack.

TN464C (and later release) circuit packs have an option switch that must be 
set to match the entry in the Bit Rate field.
Line Coding
This field selects the type of line coding used on this facility. The setting in this 
field must match the setting on the far-end of the link, or you must have an 
intervening CSU to convert the line coding protocols. Voice calls will work even if 
line coding does not match, but a single data call will bring down the DS1 facility. 
For the TTC 2Mb CMI Trunk circuit pack, this is a display-only field showing 
cmi (coded mark inversion).
The following information is for reference. Talk with your network service 
provider or your Lucent representative to find the appropriate protocol for your 
application. 
!CAUTION:
If you change this field, you must busy out the DS1 circuit pack. You must 
also change the following screens: Route-Pattern, Access Endpoint, PRI 
Endpoint, Signaling-Group, and Trunk-Group.
NOTE:
When the DS1 circuit pack is used for ISDN service, the ISDN D-channel 
data is inverted when 
ami-basic or ami-zcs is entered and not inverted 
when 
b8zs or hdb3 is entered.

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.
Valid entries Usage

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.

 (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.

 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.
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. 
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. 
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.
