This chapter contains information and instructions required to prepare the Verilink 3010 - 300 for use. Included are initial inspection procedures, installation instructions, configuration guidelines, and connection information.
The Dual DSX requires the PRISM 3030 and 3060 to have software revision 2.5 or greater. Contact Verilink Inside Sales for software upgrade, if needed.
This manual contains information and warnings which must be followed by the user to ensure safe operation and to retain the equipment in a safe condition.
WARNING: This sign denotes a potential hazard to the operator. It calls attention to a
procedure or practice which, if not correctly performed or adhered to, could result in injury or loss of life. Do not proceed beyond a WARNING sign until the indicated conditions are fully understood and met.
CAUTION: Option modu les are susc eptible to da mage cause d by static ele ctricit y.
Use ESD (electrostatic device) precautionary measures, such as wearing static grounding straps and storing modules in the supplied antistatic bags.
This unit is carefully packaged to prevent damage in shipment. Upon receipt, inspect the shipping container for damage. If the shipping container or cushioning material is damaged, notify the carrier immediately and make a notation on the delivery receipt that the container was damaged (if possible, obtain the signature and name of the person making delivery).

2 CHAPTER 1: INSTALLATION
Option Card Installation

Unit Configuration

The 3010-300 card fits into slots 2 or 3 of a 3030 or slots 2 through 6 of a 3060.
WARNING: To prevent electric shock or damage to the unit, turn the rear panel power switch OFF before removing or installing any option modules.
To add a module to an empty slot, power the unit off and remove the cover plate. Carefully slide the new card along the guides with the component side facing down. Push the b oard i n until the facepl ate rest s again st the rea r panel . Ensure that it seats without displacing the flexcable connector. Then, insert the screws.
If resistance is encountered when inserting the card, remove the card and verify that there are no obstructions in the path. Also check for bent or damaged pins in the connectors on either the module or the chassis.
Configuration is performed using any of the following methods:
The front pa nel LCD inter face (refer to ch apter Operat ion on page 3) .
A terminal connected to the SUPV or the NMS port (refer to chapter Terminal Operation on page 7).
The 3030 and 3060 provide non-volatile memory retention of unit configuration in the event of power failure. This feature allows the unit to automatically restore normal service following a power loss; however, when the unit is stored without power for an extended period, the battery may drain and some parameters may become corrupted.

Dual DSX Connection

Network Disconnection

Therefore , when the uni t is first received for instal lation or if power has not been applied for an extended period, a factory default maintenance reset operation should be performed on the unit. Refer to the procedures detailed in section Maintenance Reset of chapter Operation of the 3030 or 3060 manual.
The Dual D SX card provides a DSX-level inte rface whic h allows exte nding the digital service to a variety of equipment types.
The Dual DSX interface connection is not designed to interface directly with a telc o facility.
A typical PRISM 3030/3060 installation can include high-speed digital data, analog voice, and with the addition of the Dual DSX card, digital voice or data to a PABX or other DSX interface (A single DSX interface is available with the T1-DTE option.).

Selects the type of framing for the DSX port. The 3030 and 3060 permits framing conversion from the DTE to the Network and from the Network to the DTE (D4 to ESF and ESF to D4). Newer ESF spans can support older D4 equipment. Using ESF framing allows the user and the telco access to the increased serviceability and information available through the FDL protocols. The choices are D4
and ESF.
Selects the type of line coding for the DTE side of the unit. The choices are AMI and B8ZS.
Specifies the DTE DSX1 interface output pre-emphasis. The choices are 0 –110 ft 111– 220 ft, 221–330 ft, 331–440 ft, 441 – 550 ft, 551– 660 ft, and > 660 ft.
These can be set IDLE or THRU (Only channels currently mapped to that port or available are shown.). Channels assigned to other ports can only be changed from that port’s configuration menu. Choices for the unassigned channels are IDLE and THRU. The default is al l channels IDL E
.
IDLE
This selection does not allocate a channel to that port. Sets the specified channel to transmit idle code on the DSX port and ignore received data.

port, and the high-speed ports, including the Dual DSX port card. The network interface of the unit recognizes in-band and FDL out- of- band loopback requests. The Dual DSX also recognizes local testing and remote network management loopback test configurations as shown in Figure 2-5. The unit supports many ways to test the service to and from the unit.
Diagnostics
For the Dual DSX card, the supported loop (see Figure 2-6) is for the local interface only. The NEAR selection invokes a loopback at the interface that loops the receive data back towards the customer’s equipment. The unit also supports several other loops for other interfaces. Ports in alarm are shown on the DTE Alarms list. BERTs can be performed on the Dual DSX port.

This chapter describes the screens and menus applicable to the Dual DSX card that are associated with the PRISM 3030 and 3060 terminal interface, an application program embedded inside those units. The Operations chapter disc ussed the screens and menus associated with the front panel interface. Although the options are essentially the same for both interfaces, the terminal interface is able to show more parameters on each screen.
The Main Menu screen (Figure 3-1) lists the functional user accessible menus. To activate any menu, highlight the desired selection and press Enter. This menu and any subsequent menu can be exited by pressing the Escape key. If the Main Menu is exited, th e termina l interface program te rminates. T his is a valid way to e nd a user session. If any other menu is exite d, the previous scre en is returned .

Registers
The main body of the Alarms screen shows the current count for parameters used to trigger an alarm.
The Current co lumn shows the total of the preceding 15 one - min ute intervals. At the end of each one-minute interval, the oldest minute of the 15 - minute interval is discarded.
The Threshold column shows the values set in the Alarm screen. Any parameter that has a current value equal to or greater than its non-zero threshold generates an alarm. Any parameter with a threshold value of 0 is disabled from generating alarms.
The DTE LOS/OOF seconds field does not apply to the Dual DSX card. The parameters shown on the Alarms Screen are updated at five-second intervals.
Displays the number of seconds that the element has been without power since this value was last cleared.
Pressing Enter on (RESET) clears all Current alarm parameters, but does not change 24 - hour or 30 -day performance registers.

Channel

Allocation
Indicates the network channel assignments with Channel 1 on the left and Channel 24 on the right.
The top line identifies the slot number and the bottom line identifies the port number. A plus (+) sign in the slot position indicates either a remote communication link or the fill channels used for the alternate channel assignment mode. When channels are assigned to a port in the ALTERNATE mode (Refer to chapter Terminal Operation, section Fault and Loop Status of the 3030 or 3060 reference manual), each data channel is followed by an idle channel not assignable for other ports and marked with an x in the port position.
The T1 DTE por t is ide ntified with an aste risk (* ) in the p ort posi tion. T he Remote Comm Link is iden tified with an R in the port position. R efer to the following example.

Slot 2, Port A is assigned to network channels 1– 6 (contiguous). Slot 2, Port B is assigned to network channels 7– 12 (alternating). Slot 3, Port A is assigned to network channel 13 (voice). Slot 3, Port B is assigned to network channel 14 (voice). Slot 3, Port C is assigned to network channel 15 (voice). Slot 3, Port D is assigned to network channel 16 (voice). Slot 3, Port E is assigned to network channel 17 (voice). Slot 3, Port F is assigned to network channel 18 (voice). Network channels 19 – 23 are mapped through to the T1 DTE. Network channel 24 is assigned to the remote communication link.
