Overview

This manual descri bes the QUAD DATA module, a co mponent of Verilink’s Access System 3000 (AS3000) product line.

•

This chapter presents an overview wi th illustrations of front and rear modules.

•

Chapter 2, "Quick Set-Up" presents a sample configuration procedure, as a guide to configuring the QUAD DATA module.

•

Chapter 3, "Configuration" presents a detailed listing of all configuration options.

•

Chapter 4, "Diagnostics" details the Diagnostics Menu functions.

The QUAD DATA module is used to connect Data Terminal Equipment (DTE) or Data Communications Equipment (DCE) to a wide area network. All, or a portion of, the bandwidth of a network port on another AS3000 mo dule can be mapped to any of th e data ports on the QUAD DATA module . T he Circuit Manager function o f the SCM 3000 is required to map bandwidth fr om the QUAD DATA module, across the midplane of the shelf, to some other module.

Product Description

Four Interface

Map to Multiple

Modules

Types

The QUAD DATA module supports four high-speed sync hronous serial interfaces. Using the SCM node controller module, connections are mapped from the ports of the QUAD DATA module, across the shelf midplane, to other modules with network interfaces, such as an M1-3 T3 multiplexer, or a QUAD T1 four-port T1 CSU.

Each port of the QUAD DAT A module can be configured to support any of four synchronous serial interface protocols: V.35, X.21, RS449, or EIA 530. Each port can use a different interface protocol.

Each port can be mapped to a different destination module, supporting different type s o f network interfaces (T1/T3). The data rate for each port can be as high as 1.536 Mbit/s. The total bandwidth for the module can be as high as 6.144 Mbit/s .

Power-Up Sequence

During module initialization the front panel LEDs change state rapidly. First they will be all red, then all off except port 4 red, then a rapid countdown of red flashes from port 4 to port 1, then port 2 flashes orange three times. After a pattern of flashing green LEDs, they all flash green, then red, then go out for two seconds.

Once the module has completed the initialization self-test, the SYS LED will remain amber momentarily as the module negotiates shelf controller status.

2. Use the I2 and I3 commands to place ports 2 and 3 in service.

3. Port 1 is set to V.35 by default. Use the F2 command to select EIA 530 for port 2, then use the F3 command to select RS-449 for port 3. Since the QUAD DATA module is Data Communications Equipment (DCE), and Data Terminal Equipment (DTE) is being connected, the default setting of DCE for data port mode is correct.

4. Port 1 of the QUAD DATA module is to carry Cisco ™ router traffic. Since these routers wrap the DSU transmit clock signal back to the QUAD DATA Module on the optional third clock pair (TT in RS-449, SCTE in V.35), the port 1 clock option will be set to TT. Type “C1” and select “3” for TT. Leave ports 2 and 3 at the default value of ST.

Cloning a Circuit

With at least one ci rcuit in the SC M database, a dditional circ uits can be created by cloning an existing circuit. This method saves time.

NOTE:

When the name of an active circuit is changed in the Edit Circuit Menu, a new circuit is created which initially has the same values. If changes are made to eliminate conflicts between circ ui ts, the new circui t ca n be su cc e s sfully setup and saved. We refer to this process as “cloning”.

The example configuration describes a circuit from port 2 of the QUAD DATA module to the first 12 DS0s of T1 number 5 on the M13 multiplexer. While the first circuit is active, use these steps to clone it to the second circuit.

Enable s o r disables th e monitoring of the Data Terminal Ready lead (DTR) on a per port basis.

ST—The port samples the transmit data lead during the negative going transition of the transmit clock signal provided by the module. This is the default setting which is most often the best selection.

INV ST—The data port samples the transmit data lead during the positive going transition of the transmit clock signal provided by the module. This setting may be helpful if sampling errors occur bec a use of a long ca b le between the DTE and the QUAD DATA module, and/or when the data rate is very high.

TT—The data port samples the transmit data lead during the negative going transition of an external clock signal provided by the DTE. Thi s external cl ock is usually the transmit clock signal which the QUAD DATA module provides, simply fed down the cable to the DTE, which wraps it back to the port. This is done to control the phase relationship between the transmit data and the sampling of the data port. Most types of DTE do not wrap clock back to the DCE, therefore with most DTE this feature will not operate. When it is known that the DTE does wrap clock back to the DCE, it is advan t ageous to use this feature, as sampling errors caused by cableinduced phase angles are prevented.

If enabled, the QUAD DATA m odule will declare a Lo ss O f Signal (LOS) alarm whenever the DTR lead is not asserted by the DTE. This feature allows the detec tio n of a DTE failure or disconnected DTE cable.

When not forced, DSR is on if DTR is presented by the DTE and no red alarm condition exists.

Allows the RTS or CT S lead to be forced on.

When not forced, CTS is on if RTS is presented by the DTE and no red alarm condition exists.

Allows the Data Carrier Detect (DCD) or Local Loopback (LL) leads to be forced on.

If loopbacks are disabled, operator requests for remote loopbacks and received loop codes are ignored. Enable loopbacks is most often the best selection.

If the port is in DCE mode, allows the Indication lead (I) to be forced on. (Indication combines the functions of CTS and DCD). DTE mode is not supported, the lead called Control (C) can not be force d on.

In DCE mode, this option allows DSR to be forced on—the QUAD DATA module provides DSR and ignores the true state of DTR.

In DTE mode, this option allows DTR to be forced on as an output to the connected device regardless of the actual state of DS R .

In DCE mode, this option allows CTS to be forced on—the QUAD DATA module provides CTS and ignores the true state of RTS.

In DTE mode, this option allows RTS to be forced on as an output to the connected device.

In DCE mode, allows DCD to be forced on. Normally DCD is on only when a circuit is built from the QUAD DATA port to a network port on another module.

In DTE mode, allows LL to be forced on. Force LL on only for testing.

Because it is used to connect other devices to a WAN (Wide Area Network), the QUAD DATA module actually is Data Communications Equipment, rega rdless of the selection for the DCE/DTE mode option. Any device receiving synchronous serial data from a WAN must and will output t hat data a t the rate at which it is received. The mode option can be used to make the QUAD DATA port behave as DTE, but careful consideration should be given to the implications for timing the shelf.

In DCE mode, allows TM indication to the DTE to be forced on. Use this feature only for testing.

In DTE mode, allows a request for a Remote Loopback to be forced on. Use this feature only for testing.

DCE Mode

When configured as DCE, a QUAD DATA port outputs the information arriving from the WAN on the Receive Data pair, in perfect synchronization with the Receive Clock which it also outputs.

pair). In a synchronous interface there must al ways be a clock related to each datastream. When in DTE mode, the QUAD DATA module outputs a clock which is derived from the data arriving from another location on the Terminal Timing pair (Serial Clock Transmit External in V.35). The device connected to the QUAD DATA module must use that cl ock (on TT or SCTE) to control i ts sampling of Transmit Data.

NOTE:

When it is in DTE mode, the QUAD DATA module accepts information which is to be sent to the WAN on the pair designated Receive Data. The clock presented along with that data, on the Receive Clock pair, must be used to control the transmission rate of that data on to the WAN. If the clock on the Receive Pair does not drive the transmit path, buffer over-runs and/or buffer under-runs will occur leading to a loss of data. See Figure 3-4.

Summary

Since the AS3000 shelf has a single timing source for all T1 network ports, and since the device connected to a port set for DTE must provide transmit clock, logic dictates that any QUAD DATA port configured for DTE mode must p rovide the tr ansmit clo ck for every T1 network port in that shelf. This is likely to produce undesirable complications in the network design.

When connecting a QUAD DATA port to a DCE device, a crossover cable can be used instead of putting the port in DTE mode. This method allows the QUAD DATA port to be kept in DCE mode. In this scenario, instead of the QUAD DATA port accepting a clock from the external DCE device, the QUAD DATA port provides the clock. The external DCE device must then use the clock provided by the QUAD DATA module as its transmit timing source.

If the network design requires a QUAD DATA port to provide clock to a tail circuit—use a crossover cable to connect the external DCE and put the QUAD DATA por t in DCE mode. See Figure 3-5.

If the network design requires the QUAD DATA port to be part of a tail circuit, accepting timing from a DCE device—there are two methods av ai lable:

•

Use a straight through cable to connect the DCE to the QUAD DATA port, put the port in DTE mode, and set the port to be the shelf timing source (see the section “Timing Menu”).

•

Use a crossover cable to connect the DCE to the QUAD DATA port, put the port in DCE mode, set the clock selection to TT, and set the port to be the shelf timing source (see the section “Timing Menu”).

The SCM maintains a timing table for all of the modules in each shelf of a node. This table determines the transmit clock source for each QUAD DATA module in the shelf, as well as all T1 network modules.

NOTE:

The

Loopback

A typical way to use the following steps:

1. Establish a loopback.

2. Start tra ns m i t ti n g a te s t pat te rn.

3. Reset the test error counter.

4. Observe the test error counter to see if the test pattern is received as it was sent.

a. If no errors are observed, move the point of loopback

further away to test more of the circuit path, or

b. If errors are observed, move the point of loopback closer

to determine the source of the problem.

5. Stop the test pattern, drop all loopbacks, then: a. Place the circuit back into service if all tests passed, or b. Contact the appropriate vendor if a problem was found.

The Data Port Loopback (DPL) test is a bi-directional loopback. Any Data Terminal Equipment (DTE) connected to the QUAD DATA port will receive whatever it is transmitting. If the local DTE indicates no errors, the cabling to the QUAD DATA module and the local DTE are proven good. See Figure 4-2.

When a port of the QUAD DATA module is routed to another QUAD DATA module or any type of CSU/DSU that supports industry standard DSU loop codes—far-end loopbacks are supported. When the loopback request for a fixed period of time (a few seconds).

While it is sending the loopback code, the module monitors the receive data for that port. Under ideal circumstance s, the QUAD DATA module transmits the test pattern for a few seconds, the farend device enters a loopback state, and then the QUAD DATA module briefly receives its own loopback code. This will not always occur, but if the QUAD DATA module does detect that it is receiving its own loopback request, it “knows” that the far-end loopback was successful and indicates this on the third line of the

DTE

DTE as Test Set

In addition to the tests built in to all Verilink products, many types of Data Terminal Equipment will indicate received errors and detected loopbacks. Often this equipment operates using a protocol which is transparent to the Verilink hardware and may provide additional performance information. By using loopbacks in conjunction with the information provided by the DTE, problems can often be located and corrected. A suggested troubleshooting procedure follows.

1. Connect to the DTE which is reporting errors. Establish a local Data Port Loopback and observe whether the errors cl ear.

Verilink QUAD DATA User Manual 4-5

Diagnostics

2. Follow the logic in the figure below:

Local Data Port Loopback—clears

trouble?

Yes

Go to Step 3

No

Go to Step 4

3. If a local DPL resolves the error, the local DTE and cabling are OK. Try to establish a far-end loopback.

Far-end loopback— clears trouble?

Yes

Trouble is at far end.

Go to step 5

No

Trouble is in node or network.

Go to step 6

4. If a local DPL does not clear a local problem, the defect is local. Verify cabling to the QUAD DATA module. Verify that the correct interface type has been selected. Try changing the clock option (if the port is not set for X.21). Consider the possibility that the local DTE or QUAD DATA module is defective.

5. If a local loopback clears a problem and a far-end loopback also clears the problem, the problem exists in the far-end DTE, the far-end QUAD DATA module or DSU, or the configuration of some device at the far end. Try changing the selection for the clock option (ST vs Inverted ST) in the far end DSU or QUAD DATA module. If the far end DCE is sampling near the edge of each bit presented by the far-end DTE, the local DTE would receive errors. These errors would clear during loopbacks if the local DCE is sampling correctly.

6. If a local loopback clears a problem but a far-end loopback does not clear the problem—the trouble exists in a portion of the local node outside the QUAD DATA module (less likely) or in the network (more likely). If the network facility on which the troubled circuit leaves the local site is used only for this circuit (an entire T1 for one application), do a local loopback on the network port. If this clears the problem it is in the

4-6 Verilink QUAD DATA User Manual

network. If it does not, it is in the node. If the network facility is shared between the troubled circuit and other appl icat ions; check those applications to see if they are in trouble.

Other Tests

The QUAD DATA module is always used with other application modules which have network ports. These modules also offer diagnostic functions for testing network circuits. If the procedures in this section do not resolve any issues you may have, see the manual for the module to which the data port is mapped.
