Shared mode
In shared mode, the D-channel is provided by the DCHI or MSDL card and
PRI. The hardware configuration is basically the same as the ISDN PRI
D-channel. See Figure 70 "ISL in shared mode" (page 183).
Shared mode is established through service change in LD17, prompt USR,
with the response SHA.
In the shared mode, the DCH can share signaling for no more than 382 (T1)
or 480 (E1) trunks, including digital and analog.
