CHAPTER 3 BASIC DATA ASSIGNMENT FOR ISDN
1. ISDN LINE ACCESS CODE ASSIGNMENT
To initiate seizure of an outgoing trunk, one of four methods - OGC, OGCA, LCR, LCRS - can be used in the
system. Among the four methods, however, “LCR” method alone can access an ISDN line. For this reason, be
sure to assign “LCR” as “Kind of service (SRV)” in the ASPA command. The following explains how to
program LCR data.
STEP 1: ANPD - Assign the first digit of the LCR access code for the ISDN line.
STEP 2: ASPA - Assign the LCR access code for a dummy route number.
- Any dummy route number can be used if the route number is not duplicated.
- When Sub Address Dialing is desired, assign SUB=1. (Refer to Feature “SUB ADDRESS
- PRESENT”)
- An example “Sub Address Dialing” from a station is shown below.
- A station user may dial the Sub Address when he/she uses the ISDN trunk access code
with SUB=1. The call will be originated after Register Inter Digit Timer value if the
station user does not dial Sub Address.
- The Register Inter Digit Timer is determined by ASYD SYS1 INDEX 129. (Default data =
6 seconds.)
STEP 3: AMND- Assign the Maximum Necessary Digits (MND) for each Area/Office code (DC).
- DC must include ISDN trunk access code and ISDN address but not a Sub Address (SA).
- Analog/Digital Line Data (A/D) must be assigned as data 1 (Digital) for the DC which
includes ISDN trunk access code.
A/D = 1
STEP 4: ARNP - Assign the ISDN trunk access code to the ISDN Bch route number, but not a dummy route
number.
STEP 5: ARTD - Assign the following CDN data for the dummy route number.
TCL (CDN 6) = 1 or 4 (depending on the requirement)
L/T (CDN 7) = 1
AC (CDN 13) = 1
- The other CDNs may be left at default value (data 0) for the dummy route.
