Trunks and Endpoints
The Inter-Tel 5000 platform supports the following trunks, spans, gateways, and endpoints:
• Central Office (CO) [Local Exchange] Trunks: Up to 12 loop start [local exchange]
trunks can be installed in increments of four trunks per LSM-4 module. In addition, two
loop start trunks can be installed in the RJ-14 port built in on the Inter-Tel 5000 Base
Server.
• Spans: Up to six T1, T1/PRI, or E1/PRI spans can be connected through the Inter-Tel
5000 Base Server. The T1/E1/PRI module (T1M) supports a single span, and the Dual
T1/E1/PRI module (T1M-2) supports two spans of the three types.
– T1: In Database (DB) Programming each of the 24 channels of a channelized T1
span can be enabled as any of the following types of channels or circuits:
 Loop Start
 Ground Start
 DID (Direct Inward Dial)/[in Europe, DDI (Direct Dial Inward)]
 E&M (Ear and Mouth/2-way)
 OPX (Off Premises Ex
tension)
– T1/PRI: A T1/PRI span provides 23 information-bearing (B) channels and one data
(D) channel for signaling and control.
– E1/PRI: An E1/PRI span provides 30 B channels and one D channels.
• IP Devices: The Inter-Tel 5000 platform supports Inter-Tel IP endpoints, digital end-
points, and IP Single-Line Adapter (IP-SLA) devices. The Internet Protocol Resource
Application (IPRA) supplies IP functionality for the system and communicates to the
endpoints and gateways across 100Base-T Ethernet. The IPRA supports the Model
8601 Pocket PC SIP softphone, which is described in the following paragraph, but does
not support Inter-Tel legacy IP SoftPhones.
• Model 8602 Softphone Application: Model 8602 application software is distributed
separately from the system software. Performance and interoperability is equivalent to
hard IP endpoints.
• Pocket PC SoftPhone: Model 8601 is a SIP softphone that runs on selected Pocket PC
2002 (or later) Personal Digital Assistant (PDA) platforms.
• IP Gateway Trunks: The Inter-Tel 5000 platform supports Media Gateway Control
Protocol (MGCP) and Session Initiation Protocol (SIP) gateway trunks.
• Multi-Protocol IP Endpoints: A multi-protocol endpoint operates either in Inter-Tel
Proprietary (ITP) protocol mode or in SIP mode. A SIP server is required for SIP mode
operation. Multi-protocol endpoints include Models 8600, 8620, 8622, 8662, and 8690.
Multi-protocol endpoints require software licenses.
• Multi-Protocol IP Endpoints: Digital endpoints require DEI and DEM-16 equipment,
but licenses are not required. See “Digital Endpoints” on page 97.
NOTE
The two-port Loop Start Module (LSM-2) is no longer being manufactured,
but the module will be supported until phased out of use at customer sites.
NOTE
The single-port T1/E1/PRI Module (T1M) is in an end-of-life cycle, but the
module will be supported until sold out and phased out of use at customer
sites.
