1. GENERAL

This practice provides installation and maintenance information for the ADTRAN® Intelligent2-WireForeign Exchange Station/Dial Pulse Originate (2FXS/DPO PM) Dataport with Performance Monitoring, part number 1109403L2. It is a D4 compatible channel unit and operates in any standard D4 channel bank. Intelligent features requires the unit to be used in the ADTRAN ACT 2300, ACT 1900 , or standard WECO® D4 channel bank using the ADTRANLIU-3/PMcommon unit. The 2FXS/ DPO PM provides an interface between a D4 channel bank Pulse Code Modulation (PCM) backplane interface and a2-wirevoice frequency (VF) transmission and signaling facility.Figure 1 is an illustration of the 2FXS/ DPO PM. The unit is multifunctional and can be provisioned to operate in the following modes:

Supports Calling Number Delivery and other common (CLASSTM) service offerings according to TR TSY 000030 section 3.3.1.1.

2. INSTALLATION

After unpacking the unit, immediately inspect it for possible shipping damage. If damage is discovered, file a claim immediately with the carrier and then contact ADTRAN customer service (see section 6, Warranty and Customer Service).

The 2FXS/DPO PM plugs directly into an ADTRAN ACT 2300/1900 or standard D4 channel bank. No installation wiring is required. To install, grasp the 2FXS/DPO PM by the faceplate and insert it into the backplane connector until firmly seated.

Provisioning Options

Most options on the 2FXS/DPO are provisionable either manually, using internal slide switches, or electronically using a menu-drivenprogram called EASYMENU. The trunk processing options are found on internal slide Switch 7 (SW7) and can only be provisioned manually.

Manualprovisioningshouldbecompletedbefore the 2FXS/DPO is inserted into the channel bank. Electronic provisioning should be completed following installation.

Manual Provisioning

Internal slide switches SW1,2, 3, 4, and SW7 are used to manually provision and set the operational modes and options of the unit. Figure 1 displays switch locations.

Slide switches SW1 and SW2 are used to set, receive, and transmitattenuation. TableA displaystheavailableoptions.

Slide switches SW3-1,2, 3, 4, andSW3-5are used to provision the desired operation mode of the unit.

Slide switch SW4 is used to provision the trunk processing (SD), dial pulse correction (DPC), loop or ground start (GS), PLAR mode (PD3), tandem battery mode (TRB), tandem start mode (TWS), dial tone (DTG), and ringback tone (RTG).

Slide switch SW7 is used to provision the trunk processing options: make busy lead (1G), make busy closure (L), and busy trunk sleeve (S). Table B summarizes the option settings for SW3, SW4, and SW7.

Electronic Provisioning

ADTRAN EASYMENU is used to electronically provision the unit. Connect a VT 100 terminal or a computer running a terminal emulation program to the faceplate ADMIN port or REMOTE port using a standard male-to-maleRS-232cable. The settings for the ADMIN and REMOTE ports are shown inTable D.

A null modem cable is required to connect the REMOTE port directly to a terminal.

Initial Turn-up

Refer to the desired operational mode in Table C for the correct provisioning options.

Transmit Attenuation

Determine the input TLP. Then use the following formula to calculate the amount of transmit attenuation to add to the circuit:

Tx Attenuation=Input TLP + Internal Tx TLP of 4.5 dBm

For example, if an input TLP level of -3dB is to produce a level of 0dBm0 at TLP0, then the Transmit Attenuation should be set to 1.5 dB.

Receive Attenuation

Determine the output TLP. Then use the following formula to calculate the amount of receive attenuation to add to the circuit:

Rx Attenuation=Internal Rx TLP of 0 dBm) - Output

TLP

For example, if 0dBm0 at TLP0 is required to produce an Output TLP level of -3dB, then the Receive Attenuation should be set to 3 dB.Figure 2 provides an illustration of attenuation settings.

3. CONNECTIONS

The 2FXS/DPO PM occupies one card position in the D4 channel bank. The connector pin assignments are detailed in Figure 3.

4. TESTING

The 2FXS/DPO performs a self test after power on. During this time all four indicators turn On in a predefined sequence while the 2FXS/DPO verifies proper operation of critical circuits in the design. After successful completion of the self test, all indicators function in their normal mode.

Digital Loopback Test

The Digital Loopback Test is used to test loopback data coming from the network. Received data, or RNPCM, is latched in during the appropriate receive time slot. This data is then placed on the TDATA bus during the unit's transmit time slot.

Network On-hook/Off-hookTest

The Network On-hook/Off-hooktest is used to test signaling sent to the network by the unit. WhenOn-hookTest is selected,On-hooksignaling is sent to the network. WhenOff-hookTest is selected,Off-hooksignaling is sent to the Network. The customer loop is forced Onhook while this test is active.

Customer Ringing Test

The Customer Ringing Test will activate the unit's ring relay in a 2-on/4-offring cadence, providing ringing to the customer loop when a ring generator is properly connected to the channel bank.

1004 Hz DRS Tone Generation Test

The 1004 Hz DRS (Digital Reference Signal) Tone Generation test is used to send the DRS signal to the network, loop, or both. When Network is selected, the DRS is sent to the network from the unit. The far end unit should measure a 1004 Hz tone at a level determined by the circuit gain of the far end unit. When Loop is selected, the DRS is placed on the receive path. The loop receive level is determined by the following equation:

Receive Level = 0dB - Attenuation

When the option BOTH is selected, tone is placed on both the loop and the network.

Accessing Tests Through EASYMENU

The 2FXS/DPO PM has four faceplate indicators and a depressed provisioning switch. The front panel PM (Performance Monitoring) indicator Flashes during control link establishment and remainsON after the channel unit has been remotely provisioned.

If the channel unit has been remotely provisioned, the operator can alternate between the remote configuration data stored in nonvolatile memory or manual switch settings by pressing the momentary AP (Alternate Provisioning) switch located on the front panel.

The REM indicator remains ON when the channel unit is operating based on Remote Provisioning, and isOFF when based on manual switches. If the channel unit has never been remotely provisioned, the AP switch has no effect and the REM indicator remainsOFF . The REM LEDFlashes when an invalid operation mode is selected.
