IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation
21 03/12
E&M with Tone Control
Used for transmitting control tones using an RF device in lieu of a telephone line. Two pair of leads
control the high level guard tone, function tone and low level guard tone. The tones are generated by the
IPE2500A to base stations via the E&M leads.
The M lead is used to assert PTT of the device, allowing transmission of the control tones to a remote
adapter with a receiving RF device. The unit must be configured for E&M with Tone control and M lead
must be set on relay mode. Note that the HLGT duration may need to be increased to allow the RF
device time to keep up and transmit to the receiving device.
Multi-line Select (IPE2500A-MLS)
N OTES :
1. This operation requires IPE2500A-MLS Desk Set or XMLS001A Field Install Kit and
XAC0100A Mounting Kit.
2. With the MLS option installed, the DC and Relay options cannot be used.
3. With the MLS option, the SELECT button cannot be used to enter the frequency selection
mode.
The multi-line select operation allows the unit to control up to four base stations with one tone remote
unit. This feature is provided standard with the IPE2500A-MLS, and can be added to the IPE2500A via
the XMLS001A 4-Line Field Install Kit. The features include:
 Tone remote control of two to four different base stations
 Vox-detect indication for each line
 Unselect audio reference adjustment
 Multi-select transmission
 Mute unselect audio on transmit
 Unselect audio mute using a programmable button
 Two-wire or four-wire compatible
N OTE : The addition of the line select option to the IPE2500A allows the unit to control multiple base
stations with one unit using tone remote control. The option is not compatible with dc or local control
configurations.
Since the option is an ancillary device, some limitations are imposed on the operation of the unit. These
limitations include:
 The LOTL detection and parallel status updating features of the IPE2500A are not available when
the multi-line select option is installed because the IPE2500A receives a sum of the select and
unselect audio and cannot distinguish the source of the audio.
 During multi-select transmissions, the same control tones are used on each line. The unit is not
capable of generating different function tones on each line during a multi-select transmission.
 The channel aliases are shared among all lines.
 The volume control becomes a master volume for select and unselect audio. The relative level of the
unselect audio to the select audio can be adjusted during operation.
 DTMF Decode is not available.
 H.E.A.R. operation is not available.
