Introduction
This section contains background information on a variety of topics that may be useful for sys-
tem and voice mail administrators.
Environmental Requirements
Table 42 shows the ranges of environmental conditions for operation and storage of Inter-Tel
5000 platform equipment and endpoints.
System Capabilities
The Inter-Tel 5000 supports the telecommunication equipment required to provide seamless
integration into the Public Switched Telephone Network (PSTN) and the Internet.
Trunks and Spans
The Inter-Tel 5000 platform supports the trunks and multi-channel spans described in the fol-
lowing sections.
Central Office (CO) [Local Exchange] Trunks
Including the two loop start circuits built into the Inter-Tel 5000 Base Server, up to 14 loop
start trunks can be supported by the Inter-Tel 5000 platform. Up to three Loop Start Modules
(LSM) can be installed, and LSMs are available with either two or four ports.
T1/E1/PRI Spans
With three expansion bays, the Inter-Tel 5000 Base Server supports up to six T1, T1/PRI, or
E1/PRI spans. Single-port T1/E1/PRI modules (T1M) support one span each, and Dual T1/E1/
PRI modules (T1M-2) support two spans each. A T1 span supports up to 24 trunks; a T1/PRI
span supports up to 23 trunks; and, an E1/PRI span supports up to 30 trunks. Trunk options in
DB Programming include Loop Start, Off-Premises Extension (OPX), Direct Inward Dial
(DID) [Direct Dialing Inward (DDI), in Europe], T1, T1/PRI, E1/PRI, and T1/E&M.
NOTICE
Possible Malfunction Due to Overheating. Never exceed the maximum operating tem-
perature listed in Table 42. When installing the chassis and endpoints, allow a sufficient
margin for error in case of air conditioning failure, routine maintenance, plant shutdown,
etc. As a general guideline, if the conditions are suitable for office personnel, they are also
suitable for all equipment and endpoint operation. A properly controlled environment will
help to extend the operating life of the equipment.
