General Description
The PL1877A Radio Telephone Interconnect is a highly advanced DSP-based tool to connect to a public
telephone network. It can be used with a repeater or base station for initiating calls (with properly
equipped portables and mobiles) and/or receiving landline-initiated calls. With the telephone
interconnect, your wireless users can keep in contact with landline phone users.
The PL1877A provides a vast array of standard features that are optional with most telephone
interconnects. Features such as triple key access, number restricts, timers, speed dial, enhanced VOX,
built-in paging and more, mean easy operation, control of land-line communications, and user efficiency.
Because of its programmable features, the PL1877A can be used in most user environments and radio
systems.

Features of the PL1877A Microprocessor Telephone Interconnnect
• Flash signal (*#*) – Allows the mobile user to regain an in-house dial tone without releasing and
reaccessing the patch (call transfer, etc.). (Applicable on certain PBX equipment)
• Programmable Connect command – The command sequence required for connection to the patch
can be determined by parameter selection.
• Enhanced VOX mode allows the PL1877A to operate on control station and base station that
require VOX operation. In this mode, the PL1877A keys the radio on the presence of audio on the
telephone line. The telephone audio is delayed while the radio system is establishing the channel to
avoid clipping of syllables.
• Selective Signaling (Paging) – The PL1877A is equipped with the capability for analog paging.
Supported paging formats are 2-Tone, DTMF, Plectron, CTCSS\CDCSS, 2805, 1500, 5-Tone, and
custom 2-Tone.
• Last number redial – The last number dialed may be redialed by entering the command sequence
**. This feature may also be disabled by parameter selection.
• Over-beep – A beep is sounded when the mobile carrier is lost. This feature may be enabled or
disabled by parameter selection.
