Digital Endpoint Data Port Modules
As described in the following paragraphs, two types of Data Port Modules that can be con-
nected to Inter-Tel digital Models 8520 and 8560, Executive Display, Professional Display,
Standard Display, and Associate Display endpoints.
Personal Computer Data Port Module
The optional Personal Computer Data Port Module (PCDPM) can be installed on Standard,
Associate, Executive, and Professional Display endpoints or on Models 8520 or 8560 end-
points to gain Off-Hook Voice Announce (OVHA) receive capability or to install an optional
Modem Data Port Module (MDPM)
When used in conjunction with the Inter-Tel 5000 DEI product, the PCDPM supports audio
only with v1.1 and later software. In this version of software, the serial port is not functional
on the PCDPM, and it does not transmit data, even though the name of the device suggests that
it does.
Modem Data Port Module
The optional Modem Data Port Module (MDPM) can be installed on Standard Display, Execu-
tive Display, Model 8520, or Model 8560 endpoints for attaching a modem-equipped data
device or a single line endpoint. The MDPM requires a PCDPM.
The Model 8416 Mini-DSS connects to Model 8520 or Model 8560 digital endpoints without
PCDPM and MDPM devices.
Single Line Endpoints
Industry-standard, single line DTMF endpoints can be installed on the system and/or used as
an off-premises extension (OPX). On-premises single line circuits can be used for installing
AC-ringing single line endpoints, playback devices, and other single line devices.
Single line endpoints are connected to Single-Line Adapter (SLA) circuits, which are in turn
connected to available DEM-16 circuits. Off-premises stations can be connected to SLAs or
T1/E1/PRI modules.
• Each SLA can support any combination of up to two single line endpoint or DID
devices.
• T1/E1/PRI module circuits can be used for installing off-premises single line endpoints.
Types of Single Line Endpoints
Industry-standard, single line endpoints can be installed on the system and/or used as an off-
premises extension (OPX). An on-premises single line endpoint can be an AC-ringing single
line endpoint, a playback device, and other single line device.
Single line dual-tone multi-frequency (DTMF) endpoint users gain access to system features
by hookflashing (pressing and releasing the hookswitch quickly) and entering feature codes.
