•
For the pure DDCH configuration, with four DDCH interfaces (port 1
enabled), define four MSDL on card numbers 2, 4, 6, and 8 using port
1.
•
For the pure DCHI configuration, with four DCHI interfaces (port 1
enabled), define four DCHI on card numbers 2, 4, 6, and 8 using port
1.
•
For the mixed configuration, with two DDCH interfaces and two DCHI
interfaces, define two MSDL on card numbers 2 and 4 using port 1,
and 2 DCHI on card numbers 6 and 8 using port 1.

For the example described in
Table 9 "DDCH and DCHI fixed allocation
map (face-to-faceplate of the E1/T1 card) four span example with package
418 equipped" (page 45)
, define MSDL or DCHI in the system software as
follows:
•
for the pure configuration of four DDCH interfaces (port 0 and 1
enabled), define two MSDL on card numbers 2 and 4 using ports 0 and
1
•
for the pure configuration of four DCHI (onboard) interfaces (port 1
enabled), define four DCHI on card numbers 1, 2, 3 and 4 using port 1
•
for the mixed configuration of two DDCH interfaces and 2 DCHI
(onboard) interfaces, define one MSDL on card number 2 using ports 0
and 1 and define two DCHI on card numbers 3 and 4 using port 1
