Trunking
The Mitel platform supports various combinations of trunking across T1, T1/PRI, and E1/PRI
spans, IP gateway trunks, and loop start trunks.
Trunking Capacity and Constraints
The Mitel platform supports up to 104 trunk groups in DB Programming and each trunk group
supports a variable number of CO and IP gateway trunks. Up to 208 trunks can be programmed
per trunk group in DB Programming, but the actual number of trunks that can be connected
depends on the physical constraints of the system. For capacity, see “System Capacities” on
page 4-14. For programming, refer to the Inter-Tel 5000 Features and Programming Guide, part
no. 580.8006.
For hard-wired, non-IP gateway trunking, system capacity is determined by the number of bays
equipped with T1M, T1M-2, or LSM-2 modules. The system provides three bays for multitrunk
modules in addition to two loop start trunk circuits built-in to a single port on the back of the
Base Server.
For software-licensed IP gateway trunking using SIP gateway trunks, actual capacity is
determined by the number of IP resources and the installation of enabling hardware. Without
Basic Voice Mail enabled, the Mitel CS-5200 provides 32 IP resources and the Mitel CS-5400 or
CS-5600 provides 120 IP resources. Based on requirements, the customer provides appropriate
equipment to enable IP gateway trunking. For a detailed description of the hardware and
procedures required for installation of SIP or MGCP IP gateway trunks, see “Installing SIP
Gateways” on page 5-200.
Hard-Wired (Non-IP Gateway) Trunking
In an all-trunk system equipped with required devices and licensing, the Mitel platform could
support from 2 to 182 hard-wired, non-IP gateway trunks. At the low end of the range, the
system could operate on the two loop start trunk circuits that are built-in on the chassis. No
trunk modules would be installed in the bays. At the high end of the range, 182 trunks would be
available in a system equipped with six E1/PRI spans.
