ADTRAN 1200305L1 system manual Modules V35NX-2 PLL/FIFO PLL/FIFO, Receive data Fifo empty

ATLAS 550 System Manual Section 4, User Interface Guide

MODULES (V35NX-2) > PLL/FIFO > PLL/FIFO

Read security: 5

Displays the state of the PLL and FIFO systems.

LOCK	PLL is locked (This is required to transfer data.)
RXE	Receive data FIFO empty.
RXF	Receive data FIFO full.
TXE	Transmit data FIFO empty.
TXF	Transmit data FIFO full.

MODULES (V35NX-2) > CONFIGURATION

Write security: 3; Read security: 5

All of the following configurable parameters apply to the individual V.35 ports.

MODULES (V35NX-2) > CONFIGURATION > PRT

Read security: 5

Displays the port number. There are 2 available interfaces on the Dual Nx56/64 Option Module.

MODULES (V35NX-2) > CONFIGURATION > PORT NAME

Write security: 3; Read security: 5

Accepts any alpha-numeric name up to 17 characters long, to uniquely identify each port on the Dual Nx56/64 Option Module.

MODULES (V35NX-2) > CONFIGURATION > CLK +/-

Write security: 3; Read security: 5

Controls the clock used by the ATLAS 550 to accept the transmit (TX) data from the DTE. This is usually set to NORMAL. If the interface cable is long, causing a phase shift in the data, the clock can be set to INVERTED. This switches the phase of the clock, which compensates for a long cable.

MODULES (V35NX-2) > CONFIGURATION > DATA

Write security: 3; Read security: 5

Controls the inverting of the DTE data. This inversion can be useful when operating with a high-level data link control (HDLC) protocol (often used as a means to ensure 1s density). Select either NORMAL or INVERTED. Data inversion configuration must match at both ends of the circuit.

MODULES (V35NX-2) > CONFIGURATION > CTS

Write security: 3; Read security: 5

Determines the behavior of the Clear To Send (CTS) signal. If set to NORMAL, CTS will follow the value of Request To Send (RTS). If set to FORCED ON, CTS will always be asserted.
