LED Status 

Description 

LOS/RCL 
(red) 

On 

The VNA is not receiving a T1 signal (Loss of Signal or Receive Carrier 
Loss), and does not detect an open on its T1 transmit line. 

 

Flashing
90% On 

The VNA both is not receiving a T1 signal and detects an open on its T1 
transmit line.  The frequency of flashing is approximately one Hertz. 

 

Flashing
50% On 

The VNA detects an open on its T1 transmit line, and is receiving a T1 signal.  
The frequency of flashing is approximately one Hertz. 

 

Flashing 
10% On 

The T1 transceiver on the VNA is not initialized.  The frequency of flashing is 
approximately one Hertz. 

 Off 

All of the above four conditions are not occurring. 

Connections to the Field Wiring Terminal Blocks 

69320-101 Voice Network Adapter Connections to the Field Wiring 

Connections to the field are made via the upper DB25 connector on the rear of the 10457 Series Card Rack 
assembly.  This connector can be utilized by a direct connection of a DB25 cable to the field equipment, a 
DB25 cable to a DIN rail-mounted terminal block adapter, or with the use of a DB25-to-RJ45 connector 
adapter.  The pinout definition for the DB25 connection is shown is the table below.

Included with the VNA are two DB25-to-RJ45 connector adapters.  The 21246-014 Connector Adapter 
brings the transmit pair to the RJ45 pins 1 and 2 and the receive pair to pins 4 and 5.  The 21246-008 
Connector Adapter brings the transmit pair to the RJ45 pins 4 and 5 and the receive pair to pins 1 and 2.  
These adapters permit the use of non-crossover Ethernet cables for the connections to field equipment 
utilizing these same pins on an RJ45 connector. 

Cabling to the field equipment should be a twisted pair design.
