1. Getting Started

1.1 Introduction The PNMT is a Pasolink Network Management Terminal developed by NEC for management of NEC’s Pasolink radio transmission network. The PNMT is a scaled down version of Pasolink Network Management System (PNMS) that is designed as a maintenance tool for field engineers to locally and remotely monitor alarms, control points, generate reports, and archive data, all within a familiar graphical user interface, and all in real time. The PNMT is a Mobile laptop computer fitted with NEC PNMT software package that interfaces and controls NEC series short haul radio equipment. This software package remote monitors and controls the status and configuration of an entire network with associated equipment as well as the performance of the actual microwave links.

1.3 PNMT Communication Interfaces

1.3.1 Communications

Communications between the PNMT and the radio network equipment can be

• via the LA PORT of the Pasolink equipment, • via the DSC to a remote PM node in the network.

a) LA Port Interface

On the Pasolink equipment, the LA Port is mounted on the front of the equipment.

The LA Port consists of a DB15 connector and connects to PM installed in the IDU via a serial cable to the relevant communications port of the PNMT Computer.

The LA Port has the following properties:

• Port Configuration: RS-232 • Connector type: Subminiature DB15 (female) • Bit per second rate: 1200/2400/4800/9600/19200 (default 19200) • Stop bits: 1 • Data bit length: 8 • Parity: no parity.

The following table is given cabling pin assignment of the connection between LA Port and PNMT PC.

2.17.18 Setting the MAIN LAN INTFC

This function enables you to set the 10BASE-T or 2M and its properties. When the 10BASE-T is available, you can select bandwidth for Port1 and Port2 wherein the sum of bandwidth of Port1 and Port2 is equal to or less than the bit rate (Port1+Port2< Bit Rate).

To enable the Port Setting:

There are seven items that can be executed for each port in the Port Setting menu. The function of each control is as follows.

Throughput: This function selects bandwidth for Port1 and Port2. Sum of the bandwidth of Port1 and Port2 should be less than or equal to the bit rate (Port1+Port2<=Bit Rate).

Mode: This function corresponds to the LAN interface signal

speed and mode. Those choices are applicable only when Auto Negotiation is in the OFF condition.

Flow CTRL: This function is used to restrict the quantity of the packet

sent to Switching Hub so as not to cause buffer overflow that will lead to dropped packets.

Framing: This function is used to frame the signal in G.704 E1 format. This means that signal will be framed in 64Kbps timeslots.

CAS: Channel Associated Signaling. If set to ON (1), the LAN

signal is multiplexed to the data channel excluding CAS channel area. This means that there will be a dedicated in-band signalling channel. If set to OFF(0), the LAN signal will be multiplexed to the data signal, including the CAS channel area. In other words, there will be no dedicated channel for in-band signalling.

CRC: Cyclic Redundancy Check: The method used to detect the

error of received by adding a CRC-bit to the packet frame. The CRC-bit is then checked at the receiving side.

Collision: If the LAN is set in half-duplex mode, collision is normally

reported (as event) to the NMS. Collision is not considered an alarm so it is just a status report. In case, that the collision report is not to be forwarded to the NMS, this can be masked by setting it to “Not Report”.

NOTE: CAS and CRC are only available if framing is set to ON.
