Configuration
requirements
The SIP for Packet Trunking feature requires that the SIP GSM:
• be an SM-2000, and
• contain a packet switch unit model 2 (PSU2).
• DRM IP trunking requires that the SM-2000 be a CORE700 SM,
because of all the memory that is required when all the
functionality (signaling, call processing, and bearer) is combined
onto a single SM.
Earlier versions of the switching module and packet switch unit do
not support SIP for Packet Trunking.
Recommendations
Though the GSM can be used as a bearer switching module (SM), it
is recommended that the GSM not be engineered as the bearer SM for
reliability, recovery, and performance reasons.
Note: This does not apply to the DRM/VCDX. Since there is only one
SM, is necessary to support all of the signaling and bearer
functionality on the same SM.
