Connections to the Field Wiring Terminal Blocks

69320-101VoiceNetworkAdapterConnectionstotheFieldWiring

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-mountedterminal block adapter, or with the use of aDB25-to-RJ45connector adapter. The pinout definition for the DB25 connection is shown is the table below.

Upper DB25 Connector

Pin Signal

1Tx (ring)

2Tx (tip)

5Rx (ring)

6Rx (tip)

Included with the VNA are two DB25-to-RJ45connector adapters. The21246-014Connector Adapter brings the transmit pair to the RJ45 pins 1 and 2 and the receive pair to pins 4 and 5. The21246-008Connector 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 ofnon-crossoverEthernet 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.

The Lamp Test switch turns on all LEDs on the VNA’s front panel. It is used during production of the VNA. The Lamp Test switch will not function when the VNA detects the MCU (MCU FLT LED is Off). Set the Lamp Test switch according to the following table:

Open

All front panel LEDs function normally.

 

 

Close

All front panel LEDs are ON

 

 

The Customer Disconnect function presents a well-behavedsignal on the T1 line. This signal is sometimes useful during troubleshooting and verification. Set the Customer Disconnect Enable switch according to the following table:

Open

The T1 transceiver is operating normally.

 

 

Closed

The Customer Disconnect signal is being transmitted on the T1 line. This setting disrupts the

 

T1 signal and the MCU reports a T1 line fault.

 

 

The Local Loop Back feature sometimes is used during troubleshooting. Set the Local Loop Back switch according to the following table:

Open The T1 transceiver is operating normally.

Closed The “Framer Loopback” feature of the T1 transceiver is enabled. The T1 transceiver transmits the Blue Alarm on the T1 transmit line during this condition. This setting disrupts the T1 signal and the MCU reports a T1 line fault. This setting causes the VNA to receive the T1 signal it normally would transmit, while actually transmitting the Blue Alarm.

The Remote Loop Back feature sometimes is used during troubleshooting. Set the Remote Loop Back switch according to the following table:

Open The T1 transceiver is operating normally.

Closed The “Remote Loopback” feature of the T1 transceiver is enabled. This setting disrupts the T1 signal and the MCU reports a T1 line fault. This setting causes the VNA to transmit its received T1 signal. The T1 standards mention two types of loopbacks: “line” and “payload”; this loopback is a “line” loopback.

Set the T1 Synchronous switch according to the following table:

Open The VNA is frequency locked to the received T1 signal. This setting is ignored if the VNA is both aST-BusClock Slave and a T1 Clock Slave.

Closed The VNA is not frequency locked to the received T1 signal. “Elastic store” buffers in the T1 transceiver integrated circuit either duplicate or drop a frame as needed.

Set the E1 Select switch according to the following table:

Open

The VNA uses T1 signaling.

 

 

Closed

The VNA uses E1 signaling. NOTE: Upon initial release of the VNA, this feature does not

 

function properly.

 

 

The Sample Rate Select switch configures the VNA’s codec’s sampling rate. The VNA’s codec can run at either 8,000 samples per second (8 kHz), or 16,000 samples per second (16 kHz). The VNA accepts and generates 69266-001T1 Interface wide bandwidth page audio regardless of the setting of this switch. Set the Sampling Rate Select switch according to the following table:

Open

The VNA’s codec uses 8 kHz sampling. Always use this setting if wide bandwidth paging is

 

disabled. This setting is recommended.

 

 

Closed

The VNA’s codec uses 16 kHz sampling.

 

 

Set the Reserved switches according to the following table:

Open

Use this setting to help insure future compatibility.

 

 

Closed

Do not use this setting. Using this setting may increase the risk of unexpected behavior when

 

upgrading the VNA.

Changingtoa69320-101VNAfroma69266-001T1Interface

NOTES:

1.The 69320-101VNA is not electrically compatible with its predecessors. If further information on the differences is needed, please contact theGAI-TronicsField Service Department at800-492-1212.

2.When upgrading to a 69320-101VNA, the following four upgrades are required:

Any 69266-001or69320-001VNAs must be upgraded to the69320-101VNA.

Any 69257-003,69257-002,or69257-001APIs must be upgraded to the69257-101API.

Any 69510-001,69215-003,69215-002,or69215-001backplane termination boards must be upgraded to the69510-101Termination board. Two of these boards are required per card rack.

The upgraded cards must be installed in the proper backplane slot. This task involves moving the card and the associated ribbon cable at the rear of the card rack assembly.

The 69266-001T1 Interface uses a different switch and jumper collection than the VNA. The following text states how to convert the T1 Interface switch and jumper setting to the VNA switch and jumper settings.

The 2xx/3xx Address (P2) shorting clip should be set to the 2xx position if the shorting clip on J1 of the T1 Interface is closer to the back of the T1 Interface. Otherwise, set to the 3xx position when the shorting clip on J1 of the T1 Interface is closer to the front of the T1 Interface.

NOTE: The silkscreen for J1 on the T1 interface should be blacked out; if not blacked out, then that silkscreen shows the 2xx / 3xx position reversed from the actual meaning of J1.

The Board Address (SW3) rotary switch on the VNA should match the Board Address rotary switch on the T1 Interface.

The Board Identification (SW2) rotary switch on the VNA should match the Board Identification rotary switch on the T1 Interface.

First internal DIP switch #1 (SW4) (ST-BusClock Master) should be set to CLOSED if J3 of the T1 Interface is set to ING (ignore – shorting clip towards front). Otherwise, set to OPEN when J3 of the T1 Interface is set to GEN (generate – shorting clip towards back).

First internal DIP switch #2 (SW4) (T1 Clock Master) should be set to CLOSED if J4 of the T1 Interface is set to GEN (generate – shorting clip towards front). Otherwise, set to OPEN when J4 of the T1 Interface is set to REC (receive – shorting clip towards back).

First internal DIP switch #3 (SW4) (T1 Synchronous) should be set to OPEN. First internal DIP switch #4 (SW4) (E1 Select) should be set to OPEN.

First internal DIP switch #5 (SW4) (Sampling Rate Select) should be set to OPEN. First internal DIP switch #6 (SW4) through #8 (Reserved) should be set to OPEN.

Frequently Asked Questions

Q: Is the69320-101VNA compatible with the public switched telephone network?A: No.

Q: When does the69320-101VNA generate at T1 Yellow Alarm?

A: Never.

Q: When does the69320-101VNA generate a T1 Blue Alarm?

A: Never.

Q: What is the T1 Red Alarm?

A: The T1 Red Alarm is the Loss of Signal (LOS) or Receive Carrier Loss (RCL) condition.

Q: Why do the LEDs have two labels?

A: One label is the newer vernacular; the other is the older vernacular.

Q: Why does the front panel “Lamp Test” switch not function while the VNA detects the MCU is running (the MCU FLT LED is off)?

A: That behavior is by design. That design choice helps prevent the diagnostic function of the front panel LEDs from being defeated while the system is in use.

Q: What feature does setting all front panel DIP switches to closed enable?

A: Doing so enables all four relays on the VNA, lights all LEDs on the VNA, and routes a 2.0000 kHz tone (assuming a different signal has not been loaded after power up) to all backplane audio lines and backplaneST-Busdata lines. This feature is used to approximate the maximum power consumption and electromagnetic emissions of the VNA.
