Description PL1877A Microprocessor Radio Telephone Interconnect
12/10 8
• Time out warning – If the line has been inactive for a certain period of time (a period to be set by
parameter selection), the unit sends ticks prior to disconnection to alert the user. These ticks can be
enabled or disabled.
• Mobile call origination restrictions – Calls originating from mobile sources can be permitted,
prohibited, or restricted to specific features.
• Mobile signaling – Ring signaling to mobiles may be sent to begin on any of the first 9 rings.
Setting the patch to delay mobile ring signaling by a certain number of rings allows an attendant to
answer the call on a line sharing telephone set before mobiles are alerted.
• Mobile inactivity control – If, after a conversation, the interconnect determines the mobile has been
inactive for a set period of time and the # release code has not been sent, the line releases
automatically. The inactivity time is set by parameter programming.
• Telephone line origination restrictions – Calls originating from the switched network (telephone
lines) can be permitted or prohibited.
• Toll (long distance) restriction – The PL1877A disconnects when 1, 0, 9, or any of various prefixes
(as programmed) is entered as the first digit(s) of the telephone number.
• Programmable telephone line dialing method – Either Touch Codes or dial pulses can be sent to
the land-line.
• Attendant control – An attendant (telephone sharing the same telephone line with the PL1877A)
can initiate or forward calls to the mobile users via a Touch-Code equipped, line-sharing telephone
set by dialing the attendant access code.
• Patch telephone line busy signal – When a mobile user attempts to access the patch telephone line
and the line is off-hook (in use by a line-sharing telephone set, etc.), the unit returns a busy signal to
the mobile user. The line may be accessed in this condition by the busy override code.
• CTCSS Control – The TX CTCSS disable relay can be programmed to operate on command only,
or automatically on access. This allows use of the patch without disturbing other mobile users in the
system. If the relay has been activated, (disabling CTCSS), the CTCSS may be commanded back on
in order to involve another mobile user in the telephone conversation.
• Parallel telephone line capability – The interconnect can share a telephone line with a standard
telephone set. This eliminates the need for a separate telephone line dedicated to the patch.
• Direct Access (Direct Air) – Allows the telephone line callers to be placed on the air immediately
after mobile signaling on telephone line originated calls.
• Overall Access Time Limit – The duration of access to the patch is set by parameter control.
• Automatic Station Identifier (CWID) – The patch can be configured to automatically send Morse
Code station identification information at selected intervals. The choices for these intervals are: 0–
59 minutes (periodic SID), at the end of every interconnect, or both.
• Autodial – The PL1887A can have up to 25 speed dial numbers programmed into it.
• Triple Key Access – This feature allows mobiles and portables without DTMF-equipped keypads to
answer incoming calls.
• PC Programmable – All of the PL1877A’s operating parameters can be programmed using IAPS
Software. This makes installing and setting up the PL1877A easy.
