Features and Functions
The Model LE300-IP Page/Party® Line Extender provides the following features between Page/Party® system cables.
Page Line Audio Transmission
A pair of Model LE300-IP Line Extenders provides page line audio transmission between two Page/Party® system cables. This transmission is half-duplex operation.
When the line extender detects a peak audio level equal or above a Peak Voltage Level Detection Threshold, it immediately switches audio “on” in that direction for the Transmission Direction Hold Time. Audio from the other direction is muted and ignored during that time. Audio is not switched “off” until it is continuously below the Peak Voltage Level Detection Threshold for the Transmission Direction Hold Time. The DIP switch SW2 positions 5–7, located on the Main PCBA, selects Peak Voltage Level Detection Threshold and Transmission Direction Hold Time. Refer to Figure 6 for the location of Switch SW2 on the Main PCBA and Table 1 and Table 2 below for setting options.

Page Line Audio Monitoring Output
The Model LE300-IP Line Extender provides a balanced 600-ohm audio output for monitoring audio on both the local and remote page lines. The LE300-IP mixes the local and remote page line audio and routes it to the 600-ohm audio output terminals. This audio can be sent to any external audio device (recorder, radio transmitter, amplifier, etc.) with an input impedance equal to or greater than 600 ohms. The audio output gain is adjustable using DIP switch SW3 positions 5–8 on the Main PCBA. Refer to Figure 6 for the location of Switch SW3 on the Main PCBA and the tables below for setting options.

Page Line Audio Detect Output Contact
The Model LE300-IP Line Extender provides a contact closure output that activates whenever audio is detected on the page line. The contact can be set to close when audio is detected at the local page line, the remote page line, or both. Typically this contact is used in conjunction with the Page Line Audio Monitoring Output to provide a control contact to external devices or systems when page line audio is present. The contact remains active for 1 second after the audio is no longer detected. DIP switch SW5 positions 6 and 7 enables or disables the output contact. Refer to Figure 6 for the location of switch SW5 on the Main PCBA and the tables below for setting options.

Page Line FSK Data Transmission (SmartSeries Systems)
A pair of Model LE300-IP Line Extenders re-generates the FSK data transmission between two SmartSeries Page/Party® system cables. FSK data transmission occurs on the page line allowing SmartSeries Page/Party® stations to communicate with the ADVANCE system control cabinet. For proper operation, both line extenders must have this feature enabled by setting DIP switch SW5 position 1. Refer to Figure 6 for the location of switch SW5 on the Main PCBA and Table 5 below for setting options.

Party Line Off-Hook Detection
The Model LE300-IP Line Extenders provide off-hook detection on the local Page/Party® system cable for party lines 1 through 5. An off-hook condition means a handset station is in use. If multiple line extenders are connected to the same Page/Party® system cable segment, only one off-hook detector can be enabled.
If connecting an LE300-IP to the same system cable segment as an ADVANCE Page/Party® Interface (PPI) card, disable the LE300-IP off-hook detection for party lines 1 and 2. The PPI card contains offhook detection for party lines 1 and 2.
Several shorting clips (P6–P15) are used to enable the off-hook detection feature on party line 1 through 5. Two shorting clips are associated with each party line and must be set to the same position for proper operation. The party lines 1 through 5 are configured independently.

Page/Party®Line Balance
For proper system operation, the page line and party lines 1 through 5 must be terminated with a resistance of approximately 33 ohms. The Model LE300-IP provides potentiometers to set the line balance resistance on the page line and five party lines. The line balance resistors are located on the Audio Termination Connection Module next to the page and party line terminal blocks. The line balance resistors are adjustable or can be disabled using shorting clips P1–P7.
If connecting an LE300-IP Line Extender to the same system cable segment as an ADVANCE Page/Party® Interface (PPI) card, disable the line balance for party lines 1, 2, and the page line. The PPI card provides the line balance resistors for these audio lines. Refer to Figure 3 for the location of the Audio Termination Connection Module.

Contact Closure Inputs & Relay Outputs (I/O)
Five independent contact closures can be transmitted across a pair of line extenders, meaning that an active input contact on the local line extender results in the corresponding output relay contact energizing on the remote line extender. Contact closures are bi-directional between line extender pairs.
Example: Closing a switch contact across input #1 of the local line extender results in relay output #1 activating on the remote line extender and vice versa. When the input contact is removed the corresponding output relay de-activates. No switch or jumper setting is required on the Main PCBA for configuring the I/O feature.
NOTE: Any active output contacts will deactivate if the data link is broken between the line extenders.
Echo Cancellation
Line echo (also known as electric or hybrid echo) is created by the electrical circuitry connected to a twowire (full duplex) audio system. Echo is inherent in all full-duplex audio systems and is affected by the audio line length and line impedance mismatches. The presence of audible echoes results in undesirable audio quality. This kind of quality degradation is inherent in network equipment and end-user telephone devices.
To minimize echo, the Model LE300-IP performs an echo cancellation sequence on party lines 1 through 5. The echo cancellation process takes approximately 15 seconds and is performed automatically one minute after power is applied to the LE300-IP. This delay allows all power levels to stabilize prior to performing echo cancellation.
NOTE: Signal impulses are transmitted onto the party lines during the echo cancellation process. Handset station users on a party line will hear the signals in the handset receiver. For troubleshooting purposes, the 1-minute delay may be disabled by closing DIP switch SW6 position 1. Refer to Figure 6 for the location of SW6 on the Main PCBA and Table 16 below for setting details.

Manual InitiationofEchoCanceling
Echo cancellation can be manually initiated as described below.
Press and release push button PB1 on the Main PCBA three times. The push button must be pressed for at least 0.25 second and no more than 2 seconds each time. The timing requirement is meant to prevent accidental requests. If an error is made with the push-button timing, the sequence must be repeated from the beginning.
The LEDs on the Main PCBA will indicate the progress of the echo canceling sequence. One column of LEDs turns on after each push button and press release until the sequence is started. Once the sequence is started, those LEDs remain on, and a countdown timer is displayed on the remaining LEDs. The LEDs turn OFF after the echo cancellation training sequence is complete.

Data Links between Line Extenders
The Model LE300-IP Line Extender is equipped with two different data link types for connecting to another line extender. The two data link types are a T1/E1 link via the IP network and a Low Voltage Differential Signaling (LVDS) link. The type of data link(s) used is determined by the system architecture. It is possible to use both types at the same time to achieve complex system architectures. The data link type, their intended use, and the applicable switch settings are described below.
T1/E1 over an Ethernet IP Network
This data link is used to connect two Model LE300-IP Line Extenders using an IP Network. The Model LE300-IP contains an IPmux-24, which converts the data stream from its E1/T1 port into packets for transmission over the network. These packets are transmitted via the Ethernet network port to a remote LE300-IP device that receives the packets and converts them back to their original T1/E1 format.
The LE300-IP Line Extender should be connected to the closest Ethernet switch in the network. The distance between LE300-IP Line Extender and the Ethernet switch determines the type of cable connection needed. CAT5 or CAT6 cable can be used if the distance is <100 meters. The CAT5 or CAT6 cable should be terminated with RJ-45 plugs for connection to the LE300-IP Line Extender and the Ethernet switch.
For distances exceeding 100 meters, fiber optic cable must be used. When using fiber optic cable, a small form-factor pluggable (SFP) module must be purchased separately and plugged into the IPmux-24 to provide a termination point for the fiber cable inside the line extender. The optional SFP modules are available for use with multi-mode fiber optic or single mode fiber optic cable. The SFP modules contain LC-type fiber optic connector. Refer to the SFP data sheets for maximum cable distances.
Low Voltage Differential Signaling (LVDS) Data Link
The LVDS data link connection is used to connect two or more Model LE300-IP Line Extenders in a “daisy chain” fashion when the line extenders are located within 10 meters of each other. The LVDS data link requires a straight-through CAT5e cable between line extenders. Each line extender contains an LVDS data “in” port and an LVDS data “out” port. The “out” port of the first line extender connects to the “in” port of the next line extender. This connection scheme can be used to link up to a maximum of eight line extenders and is typically used when multiple line extenders are installed in a central location.

Configuring the Data Links
The T1/E1 and LVDS data link parameters between line extenders must be configured using multiple DIP switch settings on the Main PCBA. The following sections describe each parameter and the switch settings.
T1/E1DataFormatSelection
The LE300-IP supports both T1 and E1 data line connections between units. T1 is a digital circuit that uses the DS-1 (Digital Signaling level 1) signaling format to transmit voice/data at 1.544 Mbps. T1 can carry up to 24 digital channels for voice or data. E1 is the European equivalent which carries information at the rate of 2.048 Mbps. E1 is used to transmit 30 digital channels for voice or data plus one channel for signaling, and one channel for framing and maintenance.
In the case of LE300-IP, it is always be set to T1 (default setting). DIP switch SW5 position 8 on the Main PCBA selects the data link format for the digital audio transmission between line extenders. Both line extenders must be set to the same format. Refer to Figure 6 for the location of SW5 on the Main PCBA and Table 17 below for setting details.

T1LineBuild-out Settings
This option allows the user to control the wave shape being output by the transmitter. This helps to correct problems related to long copper cables. Improperly setting this switch will cause signal degradation. The proper setting refers to the cable distance between two LE300-IP Line Extenders. In the case of LE300-IP Line Extenders it should always be set to 0–133 feet (default setting). DIP switches SW2 positions 1–3 on the Main PCBA selects line-build out parameters. Refer to Figure 6 for the location of SW2 on the Main PCBA and Table 18 below for setting details.
