ATTENTION
For the PRI Gateway, the following software package for the functionality that
allows the use of port 0 or port 1 is provided in CS 1000 Extended Media
Gateway PRI (MGP) package 418.
For the example described in
Table 10 "DDCH and DCHI fixed allocation
map (face-to-faceplate of the E1/T1 card) eight span example with
package 418 equipped" (page 46)
, define MSDL or DCHI in the system
software as follows:
•
for the pure configuration of eight DDCH interfaces (port 0 and 1
enabled), define four MSDL D-channels on card numbers 2, 4, 6 and 8
using ports 0 and 1
•
for the pure configuration of eight DCHI (onboard) interfaces (port 1
enabled), define eight DCHI D-channels on card numbers 1, 2, 3, 4,
5, 6, 7 and 8 using port 1
•
for the mixed configuration of four DDCH interfaces and four DCHI
(onboard) interfaces, define two MSDL D-channels on card number 2
and 4 using ports 0 and 1 and define four DCHI D-channels on card
numbers 5, 6, 7, and 8 using port 1
