2.2 DESCRIPTION

The Patton Electronics Model 3088RC G.SHDSL RocketLink provides high speed 2-wire connectivity to ISPs, PTTs, and enterprise environments using Symmetrical High-data-rate Digital Subscriber Line (G.SHDSL) technology.

As a symmetric DSL NTU, RocketLink DSL offers the same data rates in both directions over a single pair of regular twisted pair lines u s ing TCP AM modu lation. Line co nnection is made with an RJ-45 ja ck. The Model 3088RC is designed to fit into Patton’s 2U (3.5”) high rack chassis. This chassis uses a mid-plane architecture which allows front cards to be plugged into d iffere nt rear c ards. For m ore informa tion, refe r to the Model 1001RP14 Manual for more inf ormation on th e power supp ly option s that are available.

The NTU features exte rnally -acce ssibl e DIP switch es, lo opbac k diag no stics, SNMP/HTTP remote-management capabilities using RocketLink Plug ‘n’ Play, as well as in-band management.

2.3 SERIAL INTERFACE TYPES

The Model 3088RC versions listed below provide the following types of built-in serial interfaces:

• 3088RC/A/I provides a V.35 interface on an M/34 female connector

• 3088RC/C/AI provides a Ethernet interface on an RJ45 connector

• 3088RC/D/V/V p rov ide s a X. 21 inte rfac e on a DB-15 female connector

• 3088RC/K/K prov ides a E1 interf ace on ei ther a n RJ48 -C con nector or dual BNC

3.0 CONFIGURATION

This section describes the location and orientation of the Model 3088RC’s configuration switches and jumpers, and provides detailed instructions for all possible settings. Each 3088RC model has different configuration requirements, depending on the card’s serial interface.

You can configure the 3088RC using either the software (CLI via a 1001CC port) or the hardware (via DIP switches).

3.1 ABOUT SOFTWARE (CLI) CONFIGURATION

To use software configuration you must set DIP switches S1 and S2 to the ON position, and set DIP Switch S3 to the management address, before powering-up the RocketLink-G. When DIP switches S1 and S2 are set to ON, the RocketLink-G will operate in software-configuration mode. When set for software-configuration mode the RocketLink-G will read any configuration data previously saved to FLASH memory during system power-up. If no configuration data was previously saved to FLASH, then the Rocket Lin k-G w il l loa d th e fac tory -de fau lt c onf igu r ati on from FLASH memory. After power-up, you may use console commands or the Embedd ed Operations Channel (EOC) to mo dif y the c on f igu rati on parameters.

3.2 ABOUT HARWARE (DIP SWITCH) CONFIGURATION

To use DIP-switch configuration you must first set the DIP switches to a position other than all OFF or all ON before powering-up the RocketLink- G. When all the DIP switch es are se t to any po sitio n other than all OFF or all ON the RocketLin k-G will ope rate in ha rdwa re (DIP-s witc h)-c onf igu ration mode. In DIP-switch-configuration mode the RocketLink-G will read the DIP-switch setti ngs du rin g system st artup an d confi gure its elf ac cording to the switch settings.

Once you power-up the RocketLink-G in DIP-switch mode it will operate in DIP-switch mode until powered down. When operating in DIP-switch mode you cannot change any configuration settings:

• Changing the DIP switch settings while the device is running will not modify the operating configuration because the RocketLink-G only reads the DIP switches during s ystem startup.

• If you attempt to modify the configuration by issuing console commands, the dev ice wil l not e xecut e your c omma nds. Inste ad , the Roc ketLink-G will respond with a message indicating the device is operating in DIP-switch-configuration mode.

• If you atte mpt to mo dify any confi gu rati on parameters via the EOC (by changing (EOC variables), the RocketLink-G will not execute your changes.

3.3 CONFIGURING THE DIP SWITCHES

(V.35, X.21, and Ethernet

Models)

The Model 3088RC is equipped with three sets of DIP switches, which you can use to configure the RocketLink-G for a broad range of applications. This section describes switch locations and discusses the configuration options available.

Note By default, the RocketLink-G’s DIP switches are all set to “ON”

so the NTU can be configured via the console. If that is how you will be configuring the NTU, skip ahead to the section on configuring the console.. Otherwise, read the following sections to manually configure the DIP switch settings.

Figure 1. Location of DIP switches on Model 3088RC

The three sets of DIP switches on the Model 3088RC are referred to as S1, S2 and S3. DIP switch orientation with respect to ON and OFF positions is consistent for all switches.

The DIP switches S1 and S2 can be configured as either ON or OFF.

S1-8: TX Clock

S2-1: Front Panel Switches

The 3088RC uses front panel switches to control test modes. They may be disabled so that the 3088RC ignores them.

S2-2: Line Probe

Line probe is a mechanism that determines the highest rate (192K to 2304K) that the DSL link can reliab ly support. This takes place during training. The DSL rate will be set to the rate that line probe determines. Note that both the CO and CPE unit must have line probe enabled for it to take effect.

Line probe co uld be us ed to determine the best rate the lin e will support, and then the user could set the units for that rate and disable line probe so that the rate won’t change without the us er’s knowle dge.

S2-3: Annex A/B

Annex A is typically used in North American-like networks, whereas Annex B is typically used in European-like networks. The different annexes specify different PSD (power spectral density) masks because of the difference in T1 and E1 PSDs.

S2-4 through S2-5: Clock Mode

The RocketLink-G can operate in one of three clock modes: internal, external, or receive-recover.

X.21 operation. There are a few things to note about clock modes and X.21 operation.

— One X.21 modem must be set to Receive-Recover. The other

X.21 modem must be set to either Internal or External/Network clock mode.

— The X.21 modem that is configured as Receive-Recover must

be DCE.

— The X.21 modem that is configured as Internal must also be

DCE, but if it is an External/Network clock, then the modem must be configured as DTE.

Ethernet operation. The 3088RC/C/AI model does not recover clock from the Ethernet network because it is packet-based rather than TDM. Therefore, the external clock mode is not valid.

S2-4 S2-5 Clock Mode Description

ON ON Internal The on-board oscillator in

the 3088RC provides clock for both serial and DSL lines.

OFF ON External 3088RC uses the RX clock

from the serial interface as the clock for the DSL link.

ON OFF Receive-

Recover

3088RC uses the RX cloc k from the DSL line as the clock for the serial interface .

OFF OFF Reserved

CPE-Side Modem CO-Side Modem

Modem’s X.21 Orientation

S2-6: DTE Loops

The V.35 interface provides two pins, one to request an LAL and the other to request an RDL. If DTE loops are enabled, the 3088RC/A/I will start a local loopback or a remote loopback when these pins are asserted. If DTE loops are disabled, these requests will be ignored.

S2-7: DTE Interface Type

The DTE interface type nee ds to be set based on th e rear modul e. Set to E1 if using the /K model. Set to normal if using any other model.

S3-1 through S3-8: Management Address

Each rack card in a chassis must have a unique management address. The 1001CC and 1001MC use this address to activate and deactivate the rack card's management interface. This is necessary because all rack cards in a chassis communicate over the same bus, so only one card can be active at a time.

This address can be set to any value between 0 and 255. Set S3 to the binary representation of the number (ON=0 and OFF=1). S3-8 is the most significant bit.

3.4 ABOUT SYSTEM RESET MODE

To enter system reset mode, switch all DIP switches to the OFF position and power cycle the unit. You can use a VT100 emulator configured for 19200 bps/1 stop bit/ no parity/ XON-XOFF flow control to access the console. Upon restart, you will see the message “Reset Mode”. The 3088RC automatically communicates through the 1001CC in reset mode, and does not wait for its address.

System reset mode provides two functions: software upgrades and configuration reset to factory defaults.

S2-6 Setting

ON Enabled OFF Disabled

S2-7 DTE Interface Type

ON E1 OFF Normal

Software Upgrades

The softwa re is upgra ded by wait ing for the Res et Mode m essage. Then, the user can send an Intel HEX file supplied by Patton. After the VT100 emulator has finished sending this file, the 3088RC will respond with a mes-sage stating how many errors were detected. The user may then set the DIP switches to the desired configuration and power cycle the unit to run the upgraded software.

Configuration Reset to Factory Defaults

To recover from a forgotten password, the user may reset the unit to its factory configuration. After se eing the Reset Mode message, the user should type the ‘*’ key. This will result in a ‘:’ prompt. At the prompt, the user should ent er the co mman d reset. This wil l restore the uni t to the fa ctory configuration. The unit can then be restarted with the settings in place.

3.5 CONFIGURING THROUGH THE CONSOLE

The 3088RC offers a console command line interface. To access the console, use a VT100 emulator configured to 9600 bps, 1 stop bit, no parity, and XON-XOFF flow control. Use the 1001CC to access the console. Type CTRL+B <address> <enter> to activate the console. Log into the unit using the default password. No username will be needed.

Note Log in with the default password superuser.

You can configure the following variables through the console:

• Password: The password used to login to the console.

• Circuit ID: The circuit ID communicated to other units via EOC. EOC (Embedded Operations Channel) is an out-of-band channel specified in the G.991.2 standard for SHDSL. We use standard EOC messages for our remote loopback. The 3088RC also supports proprietary EOC messages that allow a 3096RC to configure it.

• Clock Mode: The following options are available:

— Internal: The internal oscillator in the 3088RC provid es the

clock to both the serial/T1/E1 and DSL interfaces.

— External: The serial interface provides the clock for the DSL

interface (V.35, X.21). It must be set to DTE for the X.21 interface. (This mode is invalid for the Ethernet model).

— Receive Recover: The 3088RC recovers the clock from the

DSL interface and provides it to the serial/E1 interface.

• Data Rate: Both the seria l/E1 and DSL dat a rates ar e set by sp ecifying the number of 64k timeslots.

• Annex: Either G.991.2 Annex A or Annex B.

• DTE Interface Type: Either E1 or a normal serial interface.

• DSL Error Monitor Max Interval Errors: The number of errors allowed in an interval before considering the interval errored. A value of ‘0’ disables the DSL error monitor.

• DSL Error Monitor Interval Time: The length in seconds of an interval.

• DSL Error Monitor Interval Count: The number of errored intervals allowed before restarting the DSL link.

• DSL Error Monitor Total Intervals: The number of i ntervals to insp ect before disabling the error monitor.

• DSL Error Monitor Startup Delay: The length in seco nds t o wa it af ter the DSL link is established before starting the error monitor.

• Test Modes: Loopbacks (LAL or RDL) and PRBS (pseudo-random binary sequence) BER tests (511 or 511 with errors)

• Line Probe: Enable or disable Line Probe for rate adaptive applications.

The following status information is available through the command line interface:

• LEDs: Which software controlled LEDs are currently on.

• FPSW Settings: What the fro nt p a nel switches are set to (if the unit is populated with them).

• Configuration Mode: Whether the 3088RC is configured by DIP switches or software.

• DSL Link State: In Progress, Success, Deactivated, or Idle.

• DSL Sync State: Out of Sync, Acquiring Sync, In Sync, or Losing Sync.

Note DSL Link State vs. DSL Sync State—The DSL link state

describes whether the DSL is training (in progress), linked (success), deactivated (we don’t have an option to deactivate the modem, so the user should not see this), or idle.

The DSL sync state describes whether no sync words have

been found (out of sync), there are no sync word errors (in sync), or whether we are transitioning from out of sync to in sync (acquiring sync) or vice versa (losing sync). Typically, when the link is training, the sync state goes from out of sync to acquiring sync to in sync.

• DSL Actual Rate: The actual rate at which the DSL link is running (minus DSL overhead).

• DSL Line Condition: Good or Poor.

• Noise Margin Ratio: the maximum tolerable increase in external noise power that still allows for BER of less than 1x 10–7.

• DSL Error Counters: The following error counters are available:

— CRC — LOSW (Loss of Sync Word) — TX FIFO Full — TX FIFO Empty — TX FIFO Slip —TX Stuff — RX FIFO Full — RX FIFO Empty — RX FIFO Slip

Console Help Commands

The following commands are provided to help the user find the correct command:

• help: Lists all the commands that the console recognizes.

• system help: Lists all the commands that start with system that the console recognizes.

• system set help: Lists all the commands that start with system set that the console recogn iz es.

• system show help: Lists all the commands that start with system show that the console recognizes.

• dsl help: Lists all the commands that start with dsl that the console recognizes.

• dsl set help: Lists all the commands that start with dsl set that the console recognizes.

• dsl show help: Lists all the commands that start with dsl show that the console recognizes.

• dsl show errcntr help: Lists all the commands that start with dsl

show errcntr that the console recognizes.

System Configuration Commands

The following commands allow the user to configure the system:

• system set password <password>: Set s the sy ste m p assword.

• system set circuitid <circuitid>: Sets the circuit ID.

• system set clockmode <internal|external|receiverecover>: Sets the clock mode. Internal clock mode means the 3088RC provides the clock to both the DSL and the serial interface. External clock mode means the 3088RC uses the serial transmit clock as its DSL transmit clock. Receive recover clock mode means that the 3088RC uses the DSL receive clock as its DSL transmit clock and as the serial receive clock.

Note X.21 External Clock Mode—The X.21 interface expects the

DCE to provide the clock used for both transmitting data and for sampling receive data. When the 3088RC/D/V is set as a DCE, it may be used in internal or receive recover clock modes. The DSL generates a clock that is provided to the X.21 interface.

When the 3088RC/D/V is a DTE, it may be used in external clock mode. The X.21 interface needs to provide the clock. This clock is used by the DSL to sample the serial data and also to update the receive data.

The 3088RC is set for either DCE or DTE by flipping the daughter-card. The 3088RC is a DCE if DCE points toward the front of the 3088RC.

• system set dteif <normal|e1>: Set to E1 if the rear card is Model 3088RC/K/K. Set to normal for all other models.

• system set fpsw <enabled|disabled>: Enable or disable initiating test modes using the front panel switches.

The following commands allow the user to view the current system configuration:

• system show config: Shows the configuration of the entire system, including DSL and serial/T1/E1 lines.

Any changes to the sys tem config uration or the DSL co nfiguratio n will be lost on the next power cycle unless the changes are saved. The command system save config is used to save the changes.

System Status Commands

The following commands show system status:

• system show status: Shows the following system status information: LEDs, DSL test mode, front panel switch settings, DSL link state, and configurati on mo de.

DSL Configuration Commands

The following commands are used to configure the DSL:

• dsl set timeslots <1–72>: Sets the number of timeslots. The data rate is calcul ated by the equation: data-rate = #timeslots x 64k.

• dsl set annex <a|b>: Set the annex.

• dsl set lineprobe <enabled|disabled>: Enable or disable line probe.

• dsl set link <enabled|disabled>: Enable or disable the DSL port. When disabled, a DSL link cannot be established.

• dsl set loopback <off|lal|rdl>: Start or stop loopbacks.

• dsl set pattern <off|511|511e>: Start or stop PRBS generator and BER meter.

• DSL Error Monitor

The DSL error monitor i nspect s interva ls to see if the y have met the error threshold (maxint). If the error monitor finds a certain number (intcnt) of intervals that meet or exceed the error threshold, it will restart the DSL link. The error monitor will wait (startdelay) seconds after the DSL link comes up before it b egins mo nitoring erro rs. After th e startu p delay, it will

check the number of errors that hav e occurred during each (inttime) seconds to see if they meet the error threshold. The error monitor inspects (totint) intervals before it stops.

Note Setting maxint to 0 disables the error monitor and setting totint

to 0 causes the error monitor to run continuously.

The following commands configure the error monitor:

• dsl set errmon maxint <maxint>: Sets the number of errors al lowed in an interval causes it to be considered an errored interval. If this is set to ‘0’, then the error monitor is disabled.

• dsl set errmon inttime <inttime>: Sets the length of each interval.

• dsl set errmon intcnt <intcnt>: Sets the number of errored intervals that causes the DSL link to restart.

• dsl set errmon totint <totint>: Set s the number of intervals to ins pect for errors before di sabli ng the er ror moni tor. If this is set to ‘0’, then the error monitor will run continuously.

• dsl set errmon startdelay <startdelay>: Sets the number of sec onds to wait after the DSL link comes up before the error monitor starts inspecting intervals.

Changing the d at a rate (dsl set timeslots), the clock mode (system set

clockmode), the Annex (dsl set annex), or Line Probe (dsl set lineprobe), or the DSL error monitor settings will not take effect on the

DSL link until the link restarts. The dsl start command restarts the DSL link.

DSL Status Command

The dsl show status command shows the following DSL stat us inform a- tion: link stat e, sync sta te, link speed, error co unters, l ine con dition , noise margin, and test mode status.

DSL Clear Errcntrs Command

The dsl clear errcntrs command clears the error counte r s.

3.8 CONFIGURING THE E1 REAR CARD

The E1 rear card features co nfigura tion capabi lit y via hard ware swi tches and jumpers. Sec tions 4.1 and 4.2 de sc rib e al l sw it ch a nd ju mp er co nfi g urations for the 3088RC/K model. Section 4.3 describes the configuration required for your mDSL modem.

DIP Switch Configuration

The E1 card has eight internal DIP switches (S1-1 through S1-8). The DIP switches can be configured as either “On” or “Off.”

Switch S1-1 : Line Coding. Use Switch S1-1 to control the Network Line Coding options. Set these options to be the same as the Line Coding that has been provided by your Service Provider.

Line Coding Options:

• High Density Bipolar 3 (HDB3): In HDB3 coding, the transm itt er deliberately inserts a bipolar violation when excessive zeros in the data stream ar e detected. The receiver reco gni zes these special violations and dec odes th em as zeros . This method enabl es the net work to meet minimum pulse density requirements. Use HDB3 unless AMI is required in your application .

S1-1 Line Framing & Coding

Off HDB3 On AMI

• Alternate Mark Inversion (AMI): AMI coding does not inherently account for ones dens ity . To meet thi s requirement, you should ensure that the data inherently meets pulse density requirements.

Switch S1-2 : CRC-4 Multiframe. CRC-4 Multiframe uses Time Slot zero to carry CRC-4 information. When CRC-4 is enabled (ON), the u nit synchronizes to the CRC-4 multi-frame protocol.

Note When the data rate is set to 2048 Kbps, K Module transmits

user data on all 32 timeslots, ignoring framing information. In this case, Switch S1-2 will be ignored.

Switch S1-3 : Clear Channel Mode. When S1-3 is at Off position, the K Module is running in G.703 clear channel mode. When S1-3 is at On position, the K Module is running in G.704 framed mode. When the K Module is set to framed mode, channel 0 will be used to pass G.704 framing information which results in a maximum bandwidth of 1984kbps for user data.

Switch S1-4 Through S1-8 : Reserved. Reserved for future use and should be set to OFF.

Jumper Configuration

The 3088RC/K mode l has four jumper s (two position he aders): JP4, JP5, JP6, and JP7. These jump ers are used to selec t input and output impedance matching between the module and external line. See Appendix E for jumper locations.

The following is a description of the jumper settings with respect to the front panel connectors.

1. For a 75 ohm connection (coax) install JP4 - JP7 (default).

2. For a 120 ohm connection (RJ-48C) remove JP4 - JP7.

If you wish to connect the 3088RC/C/AI to another DTE device such as a 10Base-T network interface card in a PC, you must construct a 10Base-T crossover cable as shown in the diagram below.

Connecting the Line Interface. The Model 3088RC/C/AI is to be used with Patton function card access products (i.e. 1092ARC) There are two essential requirements for connecting th e line interface on Model 3088RC/C/AI:

1. These units work in pairs with one 3088RC/C/AI connected to

another 3088RC/C/AI (or IM1/I) over 2 or 4-Wire Twisted pair (2 or 4-Wire operation is determined by the front function card).

2. To function properly, the Model 3088RC/C/AI needs one or two

twisted pairs of metallic wire (two or four wire). The twisted pairs must be unconditioned, dry, metallic wire, between 19 (.9mm) and 26 AWG (.4mm) (Ap pendix B describe s cabl e require ments ) . Standard dial-up telephone circuits, or leased circuits that run through

signal equalization equipment, or standard, flat modular telephone type cable, are not acceptable.

Note T wo-Wire Modems use RJ-45 pins 4 and 5 and 4-Wire Modems

use RJ-45 pins 3, 4, 5 and 6, as shown above. Please see the Function Card User Manual for more details.

LED Status Monitors

The Model 3088RC/ C/AI feature s two LEDs that moni tor general operating status and the 10Base-T twisted pair link integrity. Figure 11 shows the LEDs located directly beneath the RJ-45 jack.

Figure 11. 3088RC Rear Panel, LED Locations

Status. Blinks yellow from one to ele ven times to indicate system stat us. Each pulse pattern is separated by a 2 second “off” period. Greater pulse patterns have higher priority (buffer saturation has greater priority than an empty MAC table). Valid system st atus es are:

• 1 pulse = system status ok

• 2 pulses = No MAC entries in the MAC address table

• 3 pulses = Clear to send (CTS) or Carrier Detect (DCD) from base unit are not asserted

• 4 pulses = IMRC2/IA buffer is saturated

• 5 pulses = WAN receive frame(s) too large

• 6 pulses = WAN receive frame(s) not Octet aligned

• 7 pulses = WAN receive frame(s) aborted

• 8 pulses = Detected WAN receive frame(s) with bad CRC

• 9 pulses = Detected LAN receive frame(s) too large

• 10 pulses = Detected LAN receive frame(s) not Octet aligned

• 11 pulses = Detected LAN receive frame(s) with bad CRC

After a statu s c od e is dis pl aye d ei ght times and the associated condition is removed, the status code will no longer appear.

Link. Glows green to indicate good link integrity on the 10Base-T twisted pair line.

This section d escrib es the fu nctio ns of the Mo del 100 1R14 rack chas sis, tells how to install front and rear Model 3088RC Series cards into the chassis, and how to connect to the twisted pair interface and the serial interface.

4.1 THE MODEL 1001R14 RACK CHASSIS

The Model 1001R14 Rack Chassis (Figure 17) has fourteen short range modem card slots, plus its own power supply. Measuring only 3.5” high, the Model 1001R14 is designed to occupy only 2U in a 19” rack. Sturdy front handles allow the Model 1001R14 to be extracted and transported conveniently.

Figure 17. Model 1001R14 Rack Chassis with power supply

The Rack Power Supply

The power supply included in the Model 1001R14 rack uses the same mid-plane archit ec ture as the modem cards . The fron t card of the powe r supply slides in from the front, and the rear card slides in from the rear. They plug into one another in the middle of the rack. The front card is then secured by thumb screws and the rear card by conventional metal screws.

There are no user-serviceable parts in the power supply section of the Model 3088RC Series. Voltage setting changes and fuse replacement should only be performed by qualified service personnel. Contact Patton Electronics Technical support at (301) 975-1007 for more information.

WARNING

Powering Up Your 1001R14 Rack

Note The power supplies that come with your 1001R14 rack system

are equipped with a power entry connector on the rear card. The power supplies are Hot-Swappable, so you are not required to remove the cards from the rack while applying power to the system.

When a power cabl e is connected between the unit, and an appropriate power source, a green LED on the front panel will glow to indicate that the unit is working properly. Since the Model 1001R14 is a "hot swappable" rack, it is not neces sary for an y cards to be inst alled before app lying power. The power may be removed at any time without harming the installed cards.

Note Please refer to the Model 1001RP14 Series User Manual AC &

DC Rack Mount Power Supplies for fuse and power card

replacement information.

4.2 INSTALLING MODEL 3088RC SERIES INTO THE CHASSIS

The Model 3088RC Series is comprised of a front card and a rear card. The two cards meet inside the rack chassis and plug into each other by way of mating 50 pin card edge connecto rs. Us e the foll owing ste ps as a guideline for installing each Model 3088RC Series into the rack chassis:

1. Slide the rear card into the back of the chassis along the metal rails

provided.

2. Secure the rear card using the metal screws provided.

3. Slide the front card into the front of the chassis. It should meet the

rear card when it’s almost all the way into the chassis.

4. Push the front card gently into the card-edge receptacle of the rear

card. It should “click” into place.

5. Secure the front card using the thumb screws.

4.3 CONNECTING THE TWISTED PAIR INTERFACE

The Model 3088RC supports communication between two DTE devices as follows:

Using 24 AWG (0.5 mm) wire up to:

• 32,000 feet (9.7 km) at 192 kbps

• 18,500 feet (5.6 km) at 2.312 Mbps

Using 26 AWG (0.4 mm) wire up to:

• 23,000 feet (7 km) at 192 kbps

• 13,200 feet (4 km) at 2.312 Mbps

Two things are essential:

1. These units work in pairs. Both units at the end of the twisted pair

DSL span must be set for the same DTE rate—one unit set as CO, the other as CP.

2. To function properly, the Model 3088RC needs one twisted pair of

metallic wire. This twisted pair must be unconditioned, dry, metallic wire, between 19 (0.9mm) an d 26 AWG (0.4m m) (the higher number gauges will limit distance). Standard dial-up telephone circuits, or leased circuits that run through signal equalization equipment, or standard, flat modular telephone type cable, are not acceptable.

The interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability.

CAUTION

The RJ-45 connector on the Model 3088RC’s twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationships are shown in Figure 18.

4.4 CONNECTING THE MODEL 3088RC/A/I (V.35) SERIAL INTER-

FACE

Model 3088RC/A/I supports V.35 serial port connections. This section describes how to connect the serial ports to your V.35 equipment.

Connecting the Model 3088RC/A/I (V.35) to a “DTE” device

The Model 3088RC/A/I provides a V.35 DCE (data circuit terminating equipment) interface on a M/34 connector. As a DCE, this interface is designed to co nnect to DTE equipment, su ch as a ro ute r. When connecting the V.35 interfac e of t he Model 3088RC/ A/I to you r DTE dev ice, us e a V.35 straight-through cable. Appendix B.2 on page 61 describes pin assignments and signal sources for the Model 3088RC/A/I V.35 interface.

Connecting the Model 3088RC/A/I (V.35) to a “DCE” device

The Model 3088RC/A/I provides a V.35 DCE (data circuit terminating equipment) interface on a M/34 connector. As a DCE, this interface is designed to connect to DTE equipment, such as a router. However, connecting the 3088RC/A/I to another DCE device, such as a multiplexer or G.703 E1 NTU, requires a tailcircuit cable. When connecting the V.35 interface of the Model 3088RC/A/I to your DCE device, use a V.35 tail circuit cable . Som e ap pli ca tio ns m ay al so require the installation of a t ai lcircuit buf fer to ac cou nt fo r sm al l differences in clock frequency betwe en the 3088RC/A/I and the V.35 DCE (multiplexer).

FACE

Model 3088RC/D/V supports X.21 serial port connectio ns. This section describes how to connect the serial ports to your X.21 equipment.

Connecting the Model 3088RC/D/V (X.21) to a “DCE” or “DTE” device

The Model 3088RC/D/V provides an X.21 interface on a DB-15 female connector . The X.21 interface default conf iguration is DCE for connectio n to DTE (data terminal equipment) such as a router. However, the X.21 interface on the Model 3088 R C/D /V m ay be c onf igu r ed as DTE (data terminal equipment) for connection to DCE such as a modem or multiplexer. When connecting the X.21 interface of th e Model 3088RC/D/V to your DTE or DCE device, use an X.21 straight-through cable.

4.6 CONNECTING THE 3088RC/K/K (E1) INTERFACE

The Model 3088RC/K/K is a rear-mountable G.703/G.704 interface card that works with the Patton Model 3088RC function card. The two cards meet inside the rack chassis and plug into each other by way of mating 50 pin card edge connectors. Use the following steps as a guideline for installing each Model 3088RC/K/K and its function card mate into the rack chassis:

1. Slide the rear card into the back of the chassis along the metal rails

provided.

2. Secure the rear card using the metal screws provided.

3. Slide the front card into the front of the chassis. It should meet the

rear card when it’s almost all the way into the chassis.

4. Push the front card gently into the card-edge receptacle of the rear

card. It should “click” into place.

5. Secure the front card using the thumb screws.

4.7 CONNECTING THE 3088RC/C/AI (ETHERNET) INTERFACE

The Model 3088RC/C/AI is a rear-moun table ethernet interface card. The two cards meet inside the rack chassis and plug into each other by way of matin g 50 pin ca rd edge con nectors. Us e the follo wing st eps as a guideline for installing each Model 3088RC/C/AI and its function card mate into the rack chassis:

1. Slide the 3088RC/C/AI rear card into the back of the chassis al ong

the metal rails provided.

2. Secure the 3088RC/C/AI rear card using the metal screws provided.

3. Slide the front function card into the front of the chassis. It should

meet the 3088RC/C/AI rear card when it is almost all the way into the chassis.

4. Push the front card gently into the card-edge receptacle of the rear

card. It should “click” into place.

5. Secure the front card using the thumb screws.

5.0 OPERATION

Once the Model 3088RC is properly configured and installed, it should operate transparently. These sections describes functions of the LED status indicators, and the use of the built-in loopback test modes.

5.1 LED STATUS INDICATORS

The Model 3088RC features four front panel LEDs that monitor the operation of the rack card. Figure 22 shows the front panel location of each LED. Table 1 describes each LED’s function.

5.2 TEST MODES

The 3088RC offers test modes in the form of loopbacks, PRBS pattern generators, and combinations of bo th (see Figure 22 on page 51). Figure 23 is a block diagram of the Model 3088RC with respect to test modes.

Figure 23. 3088RC Block Diagram

Loopbacks

The 3088RC supports both Local Analog Loopbacks (LAL) and Remote Digital Loopbacks (RDL). These can be initiated either from the optional front panel switches or by the console command dsl set loopback <off|lal | rdl>. The data path for the LAL is shown in Figure 24.

Figure 24. Local Analog Loopback Diagram

The data received from the serial interface is looped back before going out on the DSL line. Note that this loopback occurs after the pattern generator/BER meter. This means that running a 511 pattern in conjunction with an LAL should result in no error detected by the meter. The data path for the RDL is shown in Figure 25.

Figure 25. Remote Digital Loopback Diagram

The RDL causes the remote unit to loop the data received from the DSL line back to the DSL line.

Patterns

The 3088RC can generate and detect 511 and 511 with Error patterns. These can be initiated either by the optional front panel switches or by the console command dsl set pattern <off|511|511e>. When the pattern is started, the DSL framer uses its internal 511 pattern generator for its DSL TX data instead of the data received from the serial interface. Also, the framer’s internal BER Meter tries to detect a 511 pattern in the DSL RX Data.

Because the BER Meter always runs when the pattern generator runs, the meter will detect errors if either the pattern is not either looped back or the remote unit is not transmitting a 511 pattern.

One point to n ote is that t he way errors are g enerated in the 511E pattern generates CRC errors. This can cause the DSL error monitor to restart the link if the thresholds are set low enough.

5.3 REMOTE CONSOLE OPERATION

The PC user (near-end) may configure and verify status of the remote 3088RC (far-end) via a Remote Console session. The PC user must log onto the 3088RC (near-end) unit to establish a remote console session. Once done, the remote 3088RC (far-end) appears as a unit which is locally connected through the RS-232 console port. All commands are transmitted over the G.SHDSL link in the EOC channel.

Figure 26. Remote control session Diagram

Establishing a Remote Console Session

How to Connect . The following steps are to establish a connection to

the remote 3088RC (far-end) via Remote Console Session (RCS):

1. Configure a terminal em ulatio n prog ram ( e.g. , Hype rtermin al) on PC (near-end) for 9600 bps, 8 data bits, no parity, 1 stop bit, no flow control. Connect it to the 1001CC in the same chassis as the 3088RC (near-end).

2. At the password prompt, log in to the near-end Model 3088RC.

3. Ensure that a DSL link is established. You can verify an established DSL link by using the system show status command or by checking that the DSL LED is solid green. Upon executing the show status command, the dsl link state is shown as success if the DSL link is established.

4. At the command prompt, enter the command remote console.

5. Wait for the message Console: Remote console connection estab- lished.

— If a DS L link is not established, or for some other reason the

3088RC (far-end) does not respond in a reasonable amount of time, the foll owing messa ge appears: C onsole: Rem ote consol e timed out trying to con-nect. Enter the command remote console again.

— If 3088RC (Far End) already has an active remote console ses-

sion open, you will see the message Console: Remote console connection request rejected. This ca n also hap pen if the re mote 3088RC (far-end) has an established remote console session with the local 3088RC (near-end) which has timed out.

6. Enter the password at the password prompt for the remote console session.

Note The passwords for a local console session of the 3088RC (near-

end) and the remote console session of the 3088RC (far-end) should be different for the purpose of security.

7. You should now be l ogg ed into th e rem ot e 3 088RC (far-end) vi a th e remote console session. The communication with the remote 3088RC (far-end) is essentially the same as having a local console connection.

Note The local or remote 3088RC may be CO or CPE, as long as

there is one of each. Either the CO or CPE unit may accept a remote console connection.

Note With a remote console session open, a user at PC (far-end) is

blocked from using the local console. Upon typing anything, the 3088RC (far-end) sends a message to the PC (far-end) stating Console: Remote console connection is open.

Figure 27 is a screenshot of opening a typical remote console session:

Figure 27. Opening a typical remote console session

How to Disconnect . The remote console session ends under any of

the following conditions:

• The user enters the command logout

• A timeout period of 5 minutes elapses since the user has entered a

command to the console.

• The DSL link drops.

The response upon logging out of the remote console session with the command logout is Console: Remote console connection lost. The fol- lowing is what is di splayed u pon a user’s logg ing out of a remote conso le session after loggi ng in.

> remote console > Console: Remote console connection established.

password: ****** > logout Console: Remote console connection lost.

remote console command requests a remote console session on 3088RC (Far End)

Message informs us that we are now connected to the 3088RC (Far End) console

We can now enter commands on the remote console

The timeout peri od is a fix ed, non-c onfigurabl e par ameter of 5 minutes . If the remote 3088RC (far-end) has received no command within 5 minutes, it automatically terminates the RCS. Once the RCS is terminated, the PC (far-end) can establish a local console session if desired. However if the PC (near-e nd) wishes to re-est ab lish a R CS, it is a ble to d o so whether or not the PC (far-end) is in an activ e local sessio n, because the RCS has priority over a local console session. If the PC (near-end) establishes an RCS while the PC (far-end) is on a local session, the PC (far-end) is kicked off.

Differences in Local and Remote Control Session Behavior

Since the remote console session communication occurs over the G.SHDSL link’s EOC channel, some commands via the RCS have unusual effects.

• system upgrade: Do not issue this command via an RCS. A system

upgrade must be done via the local console connection. If you should accidentally issue this command over an RCS, the remote 3088RC (far-end) waits indefinitely for input (which is the system upgrade image) from the local co nsole port of the 3 088RC (far-e nd). If this command is entered, 3088RC (Far End) will have to be power-cycled.

5.4 SOFTWARE UPGRADE

The Model 3088RC is software upgradeable through the console port. Software images will be available in Intel Hex file fo rmat.

The software upgrade feature is available either by powering up the Model 3088RC with all DIP switch es set to the OFF position, or by enter- ing the system upgrade command on the command line interface. The software upgrade takes approximately 5 minutes to complete. The 3088RC will print ‘.’ to the screen while the software upgrade is in process. When the software upgrade completes, it will print a message stating that it is complete and the number of errors, if any, that occurred.

Errors may occur dur ing the sof tware upgrade if the i mage i s corrupt o r if there is a disruption in the console port connection. The Model 3088RC will print a mess age to the console port if it encounters any errors . In t he event of an error, the portions of the old image may have been overwritten, and the unit may not be able to boot into operational mode. However, the unit may still boot in to the software upgrade, so a new software image can still be loaded to bring the unit back to an operational state.

Here is the software upgrade procedure:

1. Remove all cards fro m the rack except f or the card th at you in tend to upgrade.

2. Obtain the software image Hex file for the 3088RC.

3. Turn off the Model 3088RC.

4. Make a note of the current DIP switch settings, then set all DIP switches to the OFF position.

5. Turn on the Model 3088RC.

6. Configure HyperTerminal for 19200 bps, 8 bits, 1 stop bit, no parity, XON-XOFF.

Do not issue this command to a far-end unit. If you were to do so, the near-end 3088RC would no longer be able to communicate with the far-end 3088RC.

CAUTION

7. Open Model 30 88RC Console (via HyperTerminal or other terminal emulation program).

>>Transfer >>Send Text File... >>Set “Files of Type:” to “All files (*.*)” >>Select 033252Z.hex

8. When the transfer completes, turn off the Model 3088RC.

9. Set the DIP switches for the proper configuration.

10.Turn on the Model 3088RC. It now operates with the upgraded software.

5.5 RESET CONFIGURATION TO FACTORY DEFAULT

The configuratio n can be reset to fa ctory defaul ts from the software res et mode. This allows a user to recover from a forgotten password. To reset to the configuration, follow these steps:

1. Power down the unit.

2. Set all DIP switches to the OFF position.

3. Connect a PC to the Console port.

4. Open a VT100 terminal emulator (such as HyperTerminal). Configure the emulator for 19200 bps,1 stop bit, no parity, X-ON X-OFF flow control.

Note The 3088RC will not wait for its address to be selected when in

software reset mode. It will automatically accept data from the 1001CC.

5. Power up the unit. The terminal should display the following message: Reset Mode.

6. Type the ‘*’ key. You will see a ‘:’ prompt.

7. Type the command reset.

8. When the command completes, the unit has been reset to factory configuration.

9. Set the DIP switches to the desired configuration. Power cycle the unit to begin using the new config urat ion.
