PAD Port Configuration

Configuring the PAD Port

 

 

 

Introduction

 

 

 

 

 

This section describes the PAD port parameters. Any parameter with an asterisk (*)

 

requires a Node boot.

 

 

 

Parameters

 

 

 

 

 

From the PAD port record, you can configure these parameters:

 

Connection Type

 

 

 

 

 

 

 

 

 

 

Range:

SIMP, DTR, DTRD, DTRP, DIMO, DIMOa, DIMOb, EMRI,

 

 

 

 

EMDC, EMCDIO

 

 

 

 

 

 

 

 

 

Default:

SIMP

 

 

 

 

 

 

 

 

 

 

Description:

Specifies the type of control signal handshaking that is required

 

 

 

 

before logical connections can be made to this port. See the

 

 

 

 

table below for information about when to use a connection

 

 

 

 

type.

 

 

 

 

 

 

 

 

 

 

 

 

 

Use Connection Type

When...

 

 

 

 

 

 

 

 

SIMP (Simple)

 

A terminal is wired to the port with a cable that has a

 

 

 

 

 

minimum of conductors (so most control signals are

 

 

 

 

missing). Such cabling provides only ground,

 

 

 

 

transmit, and receive data. Control signals from the

 

 

 

 

port are maintained high. If data restraint by control

 

 

 

 

signal is enabled, the CTS lead changes as required.

 

 

 

 

 

 

 

DTR

 

The device connected to the port provides DTR to

 

 

 

 

 

maintain the EIA connection. Remote users calling

 

 

 

 

the device through a PAD port know if the device is

 

 

 

 

disconnected or powered down, because the call is

 

 

 

 

not completed.

 

 

 

 

 

 

 

DTRD

 

DTR signal required. DCD, DSR, CTS drop for 1

 

 

 

 

 

second between calls and then return to idle state.

 

 

 

 

During the control signal drop, the port is unable to

 

 

 

 

receive calls.

 

 

 

 

 

 

 

DTRP

 

• DTR is passed end-to-end.

 

 

 

 

 

• Port raises CTS and DCD when it raises DSR.

 

 

 

 

The port does not monitor RTS.

 

 

 

 

• EIA Monitor supports DTRP.

 

 

 

 

• DTRP doesn’t support PVC connections.

 

 

 

 

• Configure PAD ports as an answer/originate pair

 

 

 

 

by selecting auto calling on the originate end.

 

 

 

 

• Supports primary handshaking only (DTR/DSR)

 

 

 

 

and should not be used with tail circuit modems.
