System components
- eight spans for pure DDCH configuration
- four to eight spans using mixed configuration
See Table 8: DDCH and DCHI fixed allocation map (face-to-faceplate of the E1/T1 card) four
span example
of four E1/T1 spans as well as the use of eight spans (using the E1/T1 expansion
daughterboard). The examples describe:
• pure configuration of DDCH
• pure configuration of DCHI daughterboard
• pure onboard DCHI software configuration
• possible mixed configuration
Important:
Any other configuration of four to eight spans that follow the allocation rules are also valid
for the PRI Gateway.

card) eight span example with package 418 equipped
the system software as follows:
• 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.
