3PASOLINK Introduction

LCT CONNECTION (1)

The Pasolink equipment can be configured controlled and monitored locally using the Local Craft Terminal (LCT). Using the LCT it is possible to monitor the local Indoor Unit and related Out Door Unit

A personal computer can be used as the LCT and terminal software like windows Hyper terminal can be used to communicate with the IDU.

The terminal software, communications parameters should be set as follows

Bits per second 9600 Data bits 8 Parity None Stop bits 2 Flow Control Hardware Emulation VT100 Video Terminal

Transmission Add CR/LE at end of line: yes Local Echo: No

(Send line ends with line feeds: yes)* (Echo typed characters locally: No)* Receiving

LCT CONNECTION (2)

The Remote Pasolink equipment (opposite station ) can be configured controlled and monitored from the local IDU using the Local Craft Terminal (LCT). Connect the LCT to the NMS/RA port. Using the LCT it is possible to monitor the Remote Indoor Unit and related Out Door Unit

Remote configuring/monitoring is not possible when the PM card is mounted or during HBER alarm condition.

A personal computer can be used as the LCT and terminal software like windows Hyper terminal can be used to communicate with the IDU.

The terminal software, communications parameters should be set as follows:

MAIN CHANNEL USAGE

#: Indicates the channels that are restricted by hardware limitations, bit rate setting or selected for LAN signal transmission. U: Indicates when the channel is used for E1 transmission. N: Indicates when the channel is not used. Inhibits alarm.

The variable bit rate type IDUs are either 16MB/s or 32Mb/s rate. In 16Mb/s type the selection is 2MBx2, 2MBx4 or 2MBx8 and 32Mb/s type the selection is 2MBx2, 2MBx4, 2MBx8 or 2MBx16. The display will show the rate selection accordingly.

BER alarm threshold (10-3:0 / 10-4:1 / 10-5:2 / 10-6:3) :

Press 7 and Enter

Press 8 and Enter

FRAME IDSelect item No.This item defines the

Frame ID of the transmit/receive signal. The Frame ID is used at the receive station to identify the correct receive signal.

As a signal with a different Frame ID cannot be received, the Frame ID of the opposite station should be set to the same ID number.

BER ALARM THRESHOLDWhen excessive BER is detected, the

IDU insert AIS into the data streams sent to the MUX equipment. Threshold value for AIS insertion can be selected as 1 x 10-3, 1 x 10-4, 1 x 10-5 or 1 x10-6. In the (1+1) Hot standby system, both

No.1 and No.2 channels should have the same Frame ID. The number of Frame IDs, which can be set, is eight (ID0 to ID7).

DSC2 can be used as a 9.6Kbps interface with RS232C / RS 422 / RS485 interface selectable.

Pasolink V4 uses six service channels in its radio overhead frame as shown in the table.

DEM INVERTWhen the ODU receive signal is down converted the signal sent

to the IDU may have a normal or inverted spectrum.
