GENERAL

Introduction The Verilink PRISM 3030 supports all data networking needs, from connection of

a single front end processor to shared access for video, frame relay, and voice. This approach gives the speed and flexibility of T1 transport through a single point of control. It may be configured for any combination of up to 10 high- or low-speed data ports, up to four 6 -channel voice application modules, and a DSX1 drop / insert port for voice/data.

Operating the PRISM 3030 is easy, with a choice of five menu driven interfaces. The front panel LCD display is described in the Operations chapter of this manual. The RS-232 connection to a local or remote terminal is explained in the Terminal Operation chapter. The 8100A Site Controller may be used for large network control or Telnet via LAN connection (refer to the 8100A reference manual).

The unit provides the T1 network connection through an advanced integral ESF CSU. Full performance T1 span monitoring enables early detection and correction of problems before they affect critical applications. The unit provides a wide range of test functions to aid in rapid fault isolation and repair. All the standard loopback functions may be implemented. The unit also responds to in-band fractional loop codes to accommodate fractional T1 service testing by the carrier. The internal BERT allows testing both the network and equipment connections.

The unit is compatible with industry standards to ensure access to any T1-provided service and to permit connection of all equipment quickly and correctly. Innovative design eliminates clocking problems on the high-speed data ports. The unit utilizes flash memory to allow firmware upgrades in the field. This eliminates taking units out of service for an extended time or returning units to the factory for updates.

The unit allows complete control of the DS1 bandwidth with flexible assignment of DS0 channels, allowing the user to program bandwidth as needed for each application.

The integral Ethernet or Token Ring management option provides for wide area LAN connectivity. When connecting local area bridging or routing devices to a T1 network, other CSU/DSUs are out of the LAN management loop. With the PRISM 3030, the critical T1 connection point is under control of the existing SNMP management system, providing seamless integration of LAN and WAN, and eliminating the need for a separate CSU / DSU management system.

Unit Configuration

Data Port Connections

Hardware switch settings are not required on this unit. Configuration is performed using any of the following methods:

✦ The front panel LCD interface (refer to the Operation chapter of this manual). ✦ A terminal connected to the SUPV or the NMS port (refer to the Terminal

Operation chapter). The unit provides 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. Note, however, that when the unit is stored without power for an extended period, the battery may drain and some parameters may become c orrupted.

Therefore, when the unit is first received for installation or if power has not been applied for an extended period of time, a factory-default maintenance reset operation should be performed on the unit. Refer to the procedures detailed in Maintenance Reset on page 22.

The unit is available with 1 to 10 high-speed data ports installed in Slots 2 and 3 on the rear panel (see PRISM 3030 Rear Panel on page 9). Each slot may contain one application module. The data ports are configured as data communications equipment (DCE) for connection to data terminal equipment (DTE) and may be equipped with any combination of V.35- or EIA-530-compatible interfaces. Pin assignments for both the V.35 and EIA-530 interfaces are given in Appendix A.

Voice Application Module Connection

Caution: FCC rules require that interconnecting cables carrying high-speed data be shielded appropriately to minimize radio frequency interference.

The FXO, FXS, and 4-Wire E&M Voice application modules support six ports that can be used to interface analog telephones, key systems, and PBXs to a T1 facility (DS0).

Connection to each type of voice application module is made through a rear-panel 25 - pair female connector, retained by a loop-and-hook fastener strap. Refer to Table 2-2, Table 2-3, and Table 2-4 for connection information.

LAN SNMP Connection

The unit may be equipped with an optional Ethernet or Token Ring interface for connection to the user’s LAN (local area network). The unit’s SNMP (Simple Network Management Protocol) agent can then be programmed to take advantage of the centralized status monitoring and alarm reporting capability of SNMP managed networks. The LAN interface is connected to Slot 1 on the rear panel.

Ethernet

The Ethernet interface is compliant with the 802.3 standard and is presented on an RJ-45 connector. The pinout is shown in Table 2-12.

Token Ring

The Token Ring interface is designed to operate on both 4 and 16 Mbps networks. For 4 Mbps operation, jumper J3 must be strapped across pins 1 and 2. For operation at 16 Mbps, jumper J3 must be strapped across pins 2 and 3. The Token Ring interface consists of a 9 - pin female connection compatible with shielded twisted pair (STP) cable and complies with ISO / IEC 8802 -5 (formerly IEEE

802.5). The pinout assignments are as follows.

Connection to unshielded twisted pair (UTP) cable may be accomplished using an appropriate STP to UTP media filter/ adapter (Verilink PN 9-1001- 056 -1). After connection to the Token Ring LAN, the unit must be powered down and then back up to allow the interface to perform a self test on the network.

Power Connection

AC Pow er

Connection

The unit is factory equipped for one of three powering options as required by the user. The 110 VAC version is supplied with a standard three-prong AC cord. The 220 VAC version is supplied with an unterminated cord. Both AC versions are fused at 1.0 ampere.

The DC power version is equipped with terminal blocks for power connection and is fused at 2.0 amperes. In all cases, a proper ground should be connected to the GND terminal.

Remove power before checking fuses.

On power up, the board initialization sequence causes a delay. During this period, the message on the front panel shows Calculating Checksum. Each voice application module adds six seconds to the delay.

1 Connect the AC power cord to an appropriate AC power receptacle. 2 Set the rear panel power ON/OFF switch to the ON position (labeled l). The green

power LED on the front panel should light after the LED initialization sequence ends. If the indicators do not light, recheck the power connections and the primary AC circuit breaker. Make sure the ON / OF F switch is in the ON position.

Front Panel Operation

Maintenance

Reset

After power is applied and the unit performs a self test, the idle display screen appears as shown in Figure 3-2. The top display line is text that can be user programmed (see User Info /Unit ID on page 42). The bottom line displays the unit serial number and the hardware / software revision numbers. The unit can be accessed by pressing any front panel key.

The PRISM 3030 provides 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. Note, however, that when the unit is stored without power for an extended period, the battery drains and some parameters might become corrupted.

Therefore, when the unit is first received for installation or if power has not been applied for an extended period, a factory default maintenance reset operation should be performed. This is done by pressing and holding the CLR button and then applying power to the unit. Hold this key until the RAM CLEARED message appears. This procedure installs the predefined ROM configuration to eliminate the possibility of data corruption. The battery is fully charged after power has been applied for 120 hours.

The maintenance reset operation sets all parameters to the factory default ROM settings and zeros all performance registers.

Password If no password has been programmed, the password prompt does not appear and

the PRISM 3030 proceeds directly to the menu system. The unit is factory shipped without a programmed password. The process of setting a password is described in Edit Password on page 41.

If a password has been programmed, the password screen appears when any key is pressed. Each character must be entered using the up and down arrow keys until the desired character is displayed. Using the up arrow, the characters scroll 0 through 9, A through Z, and a through z for a total of 62 distinct characters. When the correct charact er is disp layed, pr ess the rig ht arro w to move the cur sor to t he next position. The preceding character is accepted and disappears.

Enter Password: A

/ =Letter Select=Done = move

igure 3-2 P assword Scree n

Continue this pattern until the last character is selected. Press the right arrow once more and then press Select. If the password is correct, the unit advances into the menu system. If the password is entered incorrectly, the idle display is returned and another attempt can be made.

The password is case sensitive. Lower case and upper case characters must be entered exactly as they were programmed.

Front Panel Operation 23

Components

The PRISM 3030 front panel display consists of three components: a menu title, a menu element, and a cursor.

Main Menu

> Diagnostics

Cursor

igure 3-3 Main Menu Screen

These components are shown in the following screen using the Main Menu as an example.

Menu Title

The menu title is the general classification of user-accessible functions.

Menu Element

There are three types of menu elements. In this manual, the distinction is made by the box type shown in the menu diagrams.

✦ A large, solid box indicates user-selectable menus with lower level menu items. ✦ A dashed box lists user selectable parameters. Pressing Select executes the

displayed configuration.

Menu Element

Menu Title

✦ A small, solid box (with small type) indicates either a non- se lectable status or a

field in which a particular value can be entered. For example, refer to Main Menu on page 24. The upper level menus are shown

within a large, solid box. This indicates that these items are user-selectable menus. The lower level menus are shown within dashed boxes to indicate that these items are user-selectable parameters. The small, solid boxes under Alarm Thresholds indicate that value s can be entered in these f ields.

If the menu element contains a submenu, it is accessed by pressing Select. The menu element becomes the menu title and the next lower level in the hierarchy become s the men u elemen t. For example, if the m enu elemen t is T1 N ET Configuration, pressing Select moves T1 NET Configuration up to the menu title level and Framing Type moves up to the menu element level.

Cursor

The cursor first appears on the left side of the display as seen in the upper screen of Figure 3-4. When the element is a user-selectable function, pressing Select moves the cursor to the right with the arrow pointing left (<) as seen in the lower screen.

Timing Sets the timing source to synchronize the unit’s internal timing generators. In all

cases, slips are controlled to occur on frame boundaries at the network and /or DSX1 ports when timing synchronization is lost. The choices are as follows.

INTERNAL

The unit’s internal frequency standard is used for all timing.

NETWORK

Timing is derived from the network recovered clock (the most common selection for most applications).

T1 DTE

The unit synchronizes to the clock recovered from the DSX1 T1 DTE port. This selection only appears on units equipped with the T1 DTE option.

STATION

Timing is derived from a bipolar- or TTL-compatible clock supplied to the unit through the rear panel

STA CLK Connector

When this mode is selected, the timing rate must also be set from Station Input Timing.

SLOT X, PORT Y

Timing is synchronized to the external terminal timing clock supplied from the DTE and connected to the selected port. Selections only appear for ports installed in the unit. Ports are indicated as Slot X/Port Y, where X = 2 or 3 and Y= A or B.

Station Input

Timing

Selects the input timing and only appears when Station has been selected from the Timing menu. The choices are N×56 K, N×64K, and 1.544 MHz.

Station Timing Selects the N multiple when Station Input Timing is set to either N×56K or

N×64K and only appears when Station has been selected from the Timing menu. The N range is 1 to 24. For example, if N=2 and Station Input Timing is set to N×64K, the unit expects a 128 kHz clock on the station input port (2 ×64 = 128).

PRM Enable This field ENABLEs or DISABLEs the ANSI T1.403 Performance Report

Message functions.

26 CHAPTER 3: OPERATION

Zero Suppression Determines whether ones density insertion is activated after 15 zeros. To ensure

compliance with TR 54016, this field must be enabled. The choices are ENABLE and DISABLE.

Alarm Thresholds The unit can be programmed to generate an alarm condition based on a specific

level of performance degradation. Acceptable alarm thresholds are set for periods of 15 minutes (900 seconds). The error types listed in the following paragraphs can be preset to a value between 0 and 900 seconds. Setting a field to 0 diasbles the alarm on that statistic. To effectively disable alarm reporting, set all fields to 0.

The 15 - minute time frame is not

based on the TR 54016 or T1.403 interval boundaries, but is a time window based on the accumulated counts over the previous 15 one-minute intervals. In all cases, if the number of actual network errored sec onds in t he prev ious 15 minutes re aches the preset t hreshold for the specified error type, an alarm condition is declared.

Alarm Reset Timer

Sets the length of time after the alarm condition clears before the alarm indication is removed. A value of zero in this field does not allow the alarm to be automatically cleared. The default value is 30 seconds

Port Rate

Multiplier

The unit can operate at any data rate that is a multiple of 56 or 64 kbps. If N×64K is selected, the ones density requirements of the T1 network line must be ensured. If N×56K is selected, ones density for the selected DS0 channel is maintained. When set to DISABLE, the port is not used and no other configuration choices for that port are avai lable.

Port Rate The N parameter selects the required port bit rate in increments of 56 or 64 kbps,

depending on the selection in Port Rate Multiplier. The N multiplier ranges in value from 1 to 24. For example, if N is 23 and the base rate is 64 kbps, the data rate is 1472 kHz (64 kbps×23).

Starting

Channel

Number

Selects the starting channel in the 24 -channel DS1 bit stream. The unit automatically assigns the channels that follow according to the bit rate and the mode selected in DS0 Channel Assignment. If some channels are already allocated, the starting channel is adjusted to the first block of idle channels that matches the bandwidth to be mapped. The starting channel should be checked before bandwidth is allocated.

DS0 Channel

Assignment

Selects whether the DTE channel assignment is made as a CONTIGUOUS group or as ALTERNATE channels. Selecting ALTERNATE assures ones density.

Port

Transmit

Clock

Used to select the clock that the unit uses to sample the data transmitted from the DTE. When set to INTERNAL, the data is sampled directly with the transmit data clock that is also supplied to the DTE as Transmit Clock. The EXTERNAL option uses the external clock from the DTE. The OVERSAMPLED option is used to operate the port as a low-speed asynchronous port. In this mode, the port rate should be set to at least three times the asynchronous data rate (depending on the degree of allowable distortion for the particular DTE equipment used).

Invert Data In the invert mode (YES), transmit and receive data are inverted at the port

interface. This function can be used to guarantee ones density when the data is composed of SDLC-type protocols. The choices are YES and NO

CTS/DS R/DCD

Control

Setting any of these three fields to FORCE TRUE or FORCE FALSE allows the forcing of the port control lead output state. INTERNAL allows for normal operation as shown in Figure 3-12 on page 30.

The RS-232 low-speed port option can be ordered as a combination RS-232/232, RS-232/EIA-530, or RS-232/V.35 application module. The RS-232 port provides a synchron ous DC E interfa ce at su brate sp eeds for co nnect ion to cu stomer DTE. The data from the port is placed in a single selected DS0 channel of the T1 network data stream. For switched carrier applications, the RS-232 port provides local RTS to remote DCD control lead operation at all speeds below 64 kbps.

The RS-232 port provides a bidirectional loop for isolating problems associated with the interface. Looping the port does not affect data traffic assigned to any of the other DTE ports. The port loop can be activated from the front panel, the terminal interface, Telnet across the Ethernet or Token Ring interface, or by the reception of in-band V.54 loop code. The unit can also be instructed to transmit the in-band V.54 loop code to loop the corresponding remote end port.

The unit has an int ernal BERT tester with ten availab le stress p attern s. This capability can be used by looping one end of the DS0 channel assigned to the RS-232 port and BERT toward it from the other end. In addition, the BERT can be activated independently from loops for straight away or point to network testing. RS-232 BERT is valid only at 56 kbps and 64 kbps toward the DTE.

Figure 3-13 on page 31 is an addition to the DTE Port Configuration menu diagram. It shows the modified menu options available for the RS-232 port. The differences are explained in the following paragraphs.

The control leads on the RS-232 port function as explained in the following paragraphs.

DSR Control

Can be set to Force True, Force False, or Internal. The Internal option has DSR ON if the port is enabled and OFF if it is disabled.

DCD Control

Can be set to Force True or Internal. If set to Internal, DCD is ON when data is being received from the remote end and is OFF when idle code is being received from the far end. Setting to Force True keeps DCD ON regardless of whether data or idle code is being received.

CTS Control

Can be set to Force True or Internal. The setting of CTS Control has an effect on both the CTS control lead presented to the DTE and on the transmit data from the DTE toward the remote end.

If set to Internal the CTS control lead follows the RTS control lead from the DTE after a delay of 21 UI (±1 UI). The data transmitted to the remote end is also determined by the state of the RTS control lead. When RTS is ON, the transmit data from the DTE is sent to the remote end, and when RTS is OFF, idle code is sent to the remote end. If set to Force True the CTS control lead is always ON and the RTS control lead from the DTE is ignored. Thus the transmit data from the DTE is always sent through to the remote end.

Info

SNMP management stations are able to collect and analyze data from all network devices that comply with the SNMP protocol and to manage those devices. SNMP provides a standard means to monitor the status of all compatible network elements.

The SNMP Configuration screens are accessible if the unit is equipped with the Ethernet or Token Ring SNMP interface option. It allows for the entry of those parameters required for proper operation of the unit with an Ethernet- or Token Ring-based LAN manager.

The SNMP menu consists of alphanumeric entry only (no selectable parameters). The follo wing thre e menu it ems us e the form at show n in the IP Addres s screen. Each number has a range from 0 to 255 and is separated by a period.

TERMINAL OPERATION

Introduction This chapter describes the screens and menus of the Verilink PRISM 3030 terminal

interface, an application program embedded in the unit. The Operations chapter discussed the screens and menus associated with the front panel interface. Although the options are essentially the same for both interfaces, the terminal interface shows m ore para meters o n each sc reen.

System Description

Interface

Connection

The Terminal Interface requ ires an ANSI-com patible VT100 term inal (ASCII), or a computer running an ANSI terminal emulation program. The terminal interface utilizes ASCII break and escape functions, which are implemented differently with the various terminal emulation programs. The documentation supplied with the terminal emulation program should be consulted for further reference.

In addition to the TR 54016 and T1.403 protocols, proprietary messages can be sent over the facility data link (FDL) from the near-end unit to the far-end unit. A local RS-232 terminal connected to the unit can access a far-end unit. Thus, the remote unit can be queried for status and statistics, configured, or looped for testing as if the terminal is connected to it directly.

The terminal can be connected to either of two 6 - pin serial RS-232 ports on the unit. One of the modular ports is a pair of daisy-chain type rear panel connectors labeled NMS IN. The other port is labeled SUPV. Refer to Supervisory Port Connection on page 16 for further information. Cables are available for most typical connections. Standard cables and ordering numbers are listed in Ordering Numbers on page 121. Contact Verilink for any assistance in cable selection.

A serial bit rate of 1200, 2400, 9600, or 19200 bps can be selected using the front control panel (see Supv Bit Rate on page 42).

Modem

Compatibility

Both serial ports support the same custom protocols which allow the terminal interface or the Verilink 8100A Site Controller to request and receive performance and configuration data from the unit. The unit automatically determines which protocol is needed.

The terminal interface supports use of an AT comm and set compatible modem on either, or both, of the NMS IN and SUPV serial ports. The modem should be optioned to ignore DTR, enable auto answer, inhibit command echo, and return verbose result codes.

46 CHAPTER 4: TERMINAL OPERATION

If the unit is called and sent the break command before receiving the connect message, the modem hangs up.

Device Type and Revision

The device type (the PRISM 3030) and the revision control numbers are shown in the upper left corner. The first number is the hardware revision and the second number is the software revision. Information is displayed for the near-end unit (connected directly to the terminal) on the top line, and for the far-end unit (connected to the network T1 interface) on the second line. Refer to this information when contacting the factory with inquiries.

The far-end information is available only for Verilink products that support a proprietary message set. If the far end does not support these messages but does support the standard TR 54016 protocol, then the far-end information is displayed as GENERIC 54016 FAR END. If the far end does not respond to either proprietary or TR 54016 messages, then NO FAR END RESPONSE is displayed. If the far end echoes the FDL messages transmitted by the near-end unit, then FAR END LINE LOOP is displayed.

Interface

Start-Up

Once a compatibl e terminal is prop erly con nected to t he un it, a termin al interfa ce session is started by sending a break command or pressing Enter four times to the unit. If the NMS port is used, the unit then responds with the prompt Enter Unit Address. To activate the first (or only) unit, simply press Enter. To select a specific unit, enter the address number of the desired unit and press Enter.

The Enter Unit Address prompt times out after 10 seconds. If this happens, send another break. To select another unit, exit the current Terminal Interface session, send a break, and repeat the process. If an invalid address is entered, that address is echoed back to the terminal. Send another break to start a new session.

The Main Menu screen (Figure 4-2) is then displayed if no password has been specified. The Utilities menu (page 74) explains setting the password. In the Password screen (page 46), the correct password must be entered to obtain access to any other menu.

The password is case- sensitive.

Cursor

Controls

Field

Types

The terminal interface utilizes a highlighted cursor to make selections from menus and select fields within screens to be operated on. The cursor is moved in different ways, depending on the terminal emulation program used. Most programs allow use of the tab and shift+ tab keys. Others allow use of the four arrow keys. Once a field is highlighted, it is manipulated as described in Field Types.

For keyboards that do not have these standard keys or have only some of them, an alternate set of cursor control commands is provided. Each command is performed by pressing a letter key while holding down the Control key. Alternate commands can be freely mixed with the keyboard commands at the user’s discretion.

Ta b l e 4 - 1 Keyboard/Alternate Commands

Performance

Screens

The Perform ance scree ns display a detailed h istory of th e error param eters that are continuously monitored. The terminal interface provides display of near-end or far-end performance data using the facility data link.

The unit is equipped with a dual set of performance data registers that hold line statistics for both the telco and user. Each register set provides detailed status and performance history for the network and DTE interfaces.

The system has four Performance screens. The STANDARD 24 HOUR and the ENHANCED 24 HOUR screens allow viewing the 24-hour detailed performance history of the T1 circuit. The only difference in the two screens is in the type of performance data displayed. The STAN DARD 24 HOUR screen is shown in Figure 4-5.

Figure 4-5 Typical Performance Screen

The STANDARD 30 DAY and the ENHANCED 30 DAY screens allow viewing a 30 - day history of a particular element’s performance. These screens reference intervals by date rather than by time. To reach each of the four screen types, use the spacebar to toggle the STANDARD 24 HOUR field. The other fields are described as follows.

Element

Pressing the spacebar toggles this field for selection of either the NEAR or FAR unit as the source of performance data or the target of commands. NEAR refers to the unit the terminal is connected. FAR refers to the unit at the other end of the network T1 span.

Alarms Screen 53

Target

This two - part field determines which section of the circuit is presently displayed by toggling the spacebar. Telco registers are for viewing only and can not be changed. The four options are described as follows.

USER NET. Display the user performance registers for the network. USER DTE. Display the user performance registers for the T1 DTE. TELCO NET. Display the telco performance registers for the network. TELCO DTE. Display the telco performance registers for the T1 DTE.

Error Events

Displays the running total of ESF error events for the circuit selected in Element and is applicable only when Target is set to USER. This count accumulates until it reaches 65535 or is reset by pressing Enter with the (RESET) field highlighted.

Reset Performance Registers

Allows the elem ent reg iste rs to b e rese t and can only be us ed when the Target field is set to USER. If Enter is pressed, the following warning appears:

DELETE ALL PERFORMANCE DATA? (NO!) (YES)

To exit this screen without performing the reset function, press Enter with NO selected. To proceed with the reset function, press Enter on YES. All values for the chosen register set (NET or DTE) are then reset to zero.

Standard 24 Hour

Toggling this field with the spacebar steps through the four available performance screens.

The remainder of the fields in the Performance screen are for display only. They are defined as follows.

Status

Displays the selected T1 line status derived from the type (or absence) of errors in the received data. This status represents the immediate state of the received T1 signal and is not related to the alarm thresholds. This field shows one or more of the signal conditions listed in Table 4-3.

Completed Days

Displays the number of days included in the 30 - day totals.

Completed Intervals

Displays the number of 15- minute intervals in the last 24- hour period since the registers were last cleared (a 24 - hour period can contain up to 96 intervals).

54 CHAPTER 4: TERMINAL OPERATION

24 Hr.% Error Free

Displays t he perce ntage of error-free sec onds w ithin the last 24 hours or since the event registers were last cleared. It is based only on the ES and UAS parameters.

(Perform ance data)

The main bo dy of disp lay data con sists o f error eve nts for thre e different periods: The first display line shows the data accumulated for the current interval (from 0 to 900 seconds). The second line shows the totals for the last 24 -hour period (or the last 96 fifteen- minu te inte rvals). Th e third line sh ows the 30- d ay totals.

The remaining lines of this screen show the data for any intervals containing errors. Inter val 1 i s the mo st recently stored 15 -minute interval and interv al 96 is the oldest in the current 24- hour period. On the 30 - day screens, interval 30 is the oldest 1-day interval in the current 30- da y period. The real time (or date on 30 -day screens) of the interval beginning is shown in the first column.

If more than five errored intervals have elapsed, Page- Dn a ppears to the left of the performance data. Pressing Enter on this field displays the next five errored intervals. Page- Up appears once Page - Dn is used. Pressing Enter on Page - Up displays the previous five errored intervals. Only intervals that contained errors are displayed, which eliminates rows of zeroes. If an interval is not displayed, no errors were detected during that time period.

The parameters shown on the Performance screens are updated at five-second intervals.

Per AT&T Technical Reference TR 54016, the Standard 24 Hour and Standard 30 Day performance data consists of Errored Seconds (ES), Unavailable Seconds (UAS), Bursty Errored Seconds (BES), Severely Errored Seconds (SES), Loss of Frame Count (LOFC), and Controlled Slip Seconds (CSS).

The Enhanced 24 Hour and Enhanced 30 Day screens show data for CRC Errored Seconds (CRCES), Out of Frame Seconds (OOFS), Loss of Signal Seconds (LOSS), Alarm Indication Signal Seconds (AISS), Remote Alarm Seconds (RAS), and Bipolar Violation Seconds (BPVS).

For generic TR 54016 far-end devices, only the standard telco 24-hour performance data is displayed. 30- day data is not available.

Zero Suppression

Determines whether ones density insertion is activated after 15 zeros (rather than 175 zeros). The choices are ENABLE

and DISABLE.

T1 - NET Timing

Sets the timing source to synchronize the unit’s internal timing generators. In all cases, slips are controlled to occur on frame boundaries at the network and/or DSX1 ports when timing synchronization is lost.

NETWORK. Timing is derived from the network recovered clock (most applications

use this selection).

STATION. Timing is derived from a bipolar- or TTL-compatible clock supplied to

the unit at the rear panel STA CLK connector. When this mode is selected, the timing rate must also be set from Station Timing.

INTERNAL. The unit’s internal frequency standard is used for all timing. T1 DTE. The unit synchronizes to the clock recovered from the DSX1 T1 DTE

port. This selection only appears on units equipped with the T1 DTE option.

SLOT X, PORT Y. Timing is synchronized to the external terminal timing clock

supplied from the DTE and connected to the selected port.

Station Timing

Selects the input timing and only appears when Station is selected from the T1 - NET Timing menu. The choices are N ×56 K, N×64 K, and 1.544 MHz. A number appears to the right of this field when N ×56 K or N×64 K is select ed to indicate the rate multiplier. A value from 1 through 24 must be entered.

Remote Comm Channel

Selects a communication link to the far-end unit. If 0 is selected, communication is established over the ESF facility data link (valid only when the network interface is configured for ESF and the FDL has end -to -end integrity). For example, the entire T1 bandwidth must be available with no intervening multiplexers in the signal path blocking the FDL.

As an alternative, the communication link can be assigned to an unused idle channel. This option can be used whether the network is operating in a D4 or ESF mode.

When the remote communication is programmed to operate over a spare network channel, the following test conditions interrupt access to the far-end unit.

✦ A remote network LLB or PLB is initiated. ✦ A local network LLB is initiated.

62 CHAPTER 4: TERMINAL OPERATION

✍

✦ When the remote communication is programmed to operate over the facility data

link (FDL), the following test conditions interrupt access to the far-end unit:

● A remote network LLB is initiated.

● A local LLB is activated on the near end.

If far-end communication is interrupted for any reason while accessing the remote unit, exit and then reenter this screen to ensure that all the parameters have been updated.

T1-DTE Framing

Selects the typ e of framing for the DTE side of the elem ent. Th e choices are ESF and D4

T1-DTE Line Code

Sets the DTE side line coding. The choices are AMI

and B8ZS.

T1-DTE DSX Level

Specifies the DTE line build out signal level. The choices are 0–110 ft

111–220 ft, 221–330 ft, 331–440 ft, 441–550 ft, 551–660 ft, and > 660 ft.

D/ I Start Channel

Selects the first channel in the block of channels assigned to the T1 DTE, from 1 through 24.

Setting

IDLE sets the specified channel to transmit idle code on the T1 DTE port and ignore received data. THRU sets the specified channel to pass data from the T1 DTE port to the network and vice versa.

Signalling

The signalling option allows selection of Clear Channel or Robbed Bit signalling for each DS0. Each DS0 is set to the Clear Channel (disable) mode. This setting should not be changed for raw data channels. However, channels using Robed Bit signalling ust be specified to enable proper handling of the signalling bits. T1-DTE channels must be set to THRU to enable signalling.

In the Signalling Enabled row at the bottom of Figure4- 9 on page 60, an X indicates that signalling is enabled for that channel.

Configuration Screens 63

✍

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 (see DS0 Channel Assignment on page 66), each data channel is followed by a fill channel not assignable for other ports and marked with an x in the port position.

The T1 DTE port is identified with an asterisk (*) in the port position. The Remote Comm Link is identified with an R in the port position. Refer to the following example.

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 to 23 are mapped through to the T1 DTE. Network channel 24 is assigned to the remote communication link.

Signalling

Enabled

The signalling option allows selection of Clear Channel or Robbed Bit signalling for each DS0. Each DS0 is set to the Clear Channel DISABLE mode. This setting should not be changed for raw data channels. However, channels using Robbed Bit signalling must be specified to enable proper handling of the signalling bits. T1-DTE channels must be set to THRU to enable signalling.

In the Signalling Enabled row at the bottom of the screen, an X indicates that signalling is enabled for that channel.

64 CHAPTER 4: TERMINAL OPERATION

Alarm

Parameters

The Alarm Parameters screen (Figure 4-10) allows reviewing and setting alarm related thresholds for the selected element. These thresholds are the minimum acceptable performance levels.

Port

Parameters

The Port Configuration screen (Figure 4-11) sets the operating parameters for each high-speed port. The unit does not allow conflicting configurations for the DTE ports. Ther efore, th e selecti ons for ea ch menu item ar e restric ted to thos e that d o not conflict with the configuration of other high-speed ports or the T1 DTE Port. The default is all channels disabled

When channel assignment changes are made to the high-speed ports, to the remote communication link, or to the T1 DTE, the unit reestablishes the mapping of all channels. This interruption to traffic normally results in a brief burst of data errors on other ports.

Channel Allocation

A detailed desription of this field is described in Channel Allocation on page 63.

Port #

Selects the slot and port XY to be configured, where X = 2 or 3 and Y= A to F.

Rate Multiplier

The unit can operate at any data rate that is a multiple of 56 or 64 kbps. When N×64K is selected, the ones density requirements of the T1 network line must be ensured. W he n N

×56K is selected, the unit maintains ones density for the selected

DS0 channel.

DS0 Channel Assignment

Selects whether the DTE channel assignment is made as a CONTIGUOUS

group

or as ALTER NATE c hannels. Selecting ALTERNATE assures ones density.

Configuration Screens 67

Start Channel #

The starting channel in the 24- channel DS1 bit stream must be selected in this field. The unit then assigns the following channels automatically according to the bit rate and the mode selected in DS0 Channel Assignment. The choices are 1 through 24.

Port Rate

Selects the required port bit rate in increments of 56 or 64 kbps, depending on the Rate Multiplier setting. The N multiplier ranges in value from 0 to 24.

# of Channels

Displays the number of channels to be passed through to the T1 DTE. This number is determined by the selection in Port Rate.

Transmit Clock

Used to select the clock that the unit uses to sample the data transmitted from the DTE. When set to INTERNAL, the data is sampled directly with the transmit data clock also supplied to the DTE as Transmit Clock. The EXTERNAL option uses the external clock supplied by the DTE. The OVERSAMPLED option is used to operate the port as a low-speed asynchronous port. In this mode, the port rate should be set to at least four times the asynchronous data rate (depending on the degree of allowable distortion for the particular DTE equipment used).

V.54 Loop

Selecting Enable

allows the unit to respond to in-band V.54 loop commands. If

Disable is selected, the unit ignores these commands.

Invert Data

In the invert mode (YES), transmit and receive data are inverted at the port interface. This function can be used to guarantee ones density when the data is composed of SDLC type protocols. The choices are YES and NO.

CTS/ DSR/DCD Control

Setting any of these three fields to FORCE TRUE

or FORCE FALSE allows the forcing of the port control lead output state. INTERNAL allows for normal operation as shown in Figure 3-12 on page 30.

Alarm on DTR Loss

Selecting Enable allows the unit to go into alarm on loss of DTR. The default setting is Disable.

Trap IP Addres s

Accepts the IP address of a network device where alarm reporting traps are to be sent. Each of the four numbers range from 0 to 255 and is separated by a period.

The unit detects and reports T1 network alarms and provides several options for reporting them, one of which is SNMP traps. When a network alarm occurs, the unit sends a trap message to up to 6 destinations on the user’s network. The trap message is formatted per RFC 1157. The generic trap type is enterpriseSpecific (generic- trap = 7).

70 CHAPTER 4: TERMINAL OPERATION

When an alarm group is defined to report via SNMP, up to six Trap IP addresses can be assigned. The unit reports each alarm by transmitting an SNMP Trap to each Trap IP address. T1 network problems often cause more than one alarm type. In these cases, multiple trap messages are generated, each with a different specific trap type. The specific -trap field of each trap message is set to one of the values shown in Table 4-4.

DIAL NMS. Sends reports through a modem to an 8100A.

Primary Phone #, Secondary Phone#

ASCII strings for the primary and secondary call on alarm phone numbers used in the DIAL and DIAL NMS modes. The strings must not include the ATDT command prefix.

The unit makes three attempts to connect using the primary number. If all three attempts fail, the unit makes three attempts to connect using the secondary number (if it is not blank). If the secondary number fails, the unit waits five minutes and then attempts to communicate using the primary number again. When a connection is detected, the unit outputs the notification message and disconnects.

Element ID

Allows the entry of an ASCII string (29 characters in length) which identifies the unit to the device receiving the alarm notification messages.

Call on alarm messages are reported in the following format in the DIAL or DIRECT modes only.

86 APPENDIX B: FXS VOICE APPLICATION MODULE

Loop Start Signalling (FXS)

Idle The application module has ground applied to the tip conductor and has −48 VDC

applied to the ring conductor towards the 2 - wire loop. The 2 - wire loop is open (no DC path between the tip and ring conductors). The transmit A bit is set to 0 and the B bit is set to 1. The receive A bit (from the FXO application module) is set to 0 and the B bit is set to 1.

Ringing During ringing, the office end (FXO) changes the state of the B bit from a 1 to a 0

and holds the A bit to a 0. The FXS application module detects the change in state of the B bit and reacts by applying the ring generator to the 2- wire loop.

The ringing cadence (typically two seconds on and four seconds off) is provided from the office end and is controlled by the 0 or 1 state of the B bit. The phone rings until the call is abandoned by the calling party (FXO end) or the called party goes off-hook.

During ringing, the FXS application module is looking for an off - hook (loop closure) condition. When the FXS detects the off- hook, the FXS application module sets the A bit from a 0 to a 1. The B bit remains set at 1.

The user goes off- hook at the FXS end. The FXS unit detects the off-hook and signals the office end by changing the state of the A bit from a 0 to a 1. The B bit remains set at 1. The FXO application module responds by placing a loop closure on the 2 - wire towards the CO switch. The CO switch responds by returning dial tone to the FXS end. The user detects a dial tone and dials out using either dial pulse or DTMF. The dial pulse toggles the state of the A bit at a rate of 10 pulses per second (60 percent make and 40 percent break).

the ring conductor toward the 2 - wire loop. The 2 -wire loop is open (no DC path between the tip and ring conductors). The transmit A bit is set to 0 and the transmit B bit is set to 1. The receive A bit equals 1 and the receive B bit is ignored.

Outgoing Call

(toward T1

Carrier)

The ring conductor is grounded by the CPE equipment on the 2 - wire loop. This causes the FXS application module to transmit both A and B signalling bits equal to a 0. The network equipment responds and the FXS application module receives a signalling bit equal to 0 and a B signalling bit equal to 1.

Ground Start Signalling (FXS) 87

The received signalling state causes the FXS application module to ground the tip toward the CPE equipment. The CPE equipment removes the ring ground within 210 milliseconds. Within 1 millisecond after removing the ring ground, the CPE equipment provides loop closure on the 2 - wire loop. The FXS application module transmits both A and B signalling bits equal to 1 and enables the audio path.

Loop status of the CPE equipment is then transmitted toward the network equipment by the FXS application module using the A signalling bit (0 equals loop open and 1 equals loop closed). Dial pulses are transmitted transparently from the CPE to the network equipment in this manner.

Call

Ground Start

Incoming Call (from

network to CPE)

The CPE opens tip to ring termination which causes the FXS application module to transmit signalling bit A equal 0 and signalling bit B equal 1 towards the network equipment. After a time-out period, the network equipment determines that the CPE has disconnected. The network equipment then responds and the FXS receives an A bit equal 1 and ignores the B bit. This causes the FXS application module to open the tip, which is the idle state.

In an idle state, the FXS application module sees the following.

✦ From the network, the received A bit equal to a 1 and the B bit ignored ✦ The tip is open toward the CPE ✦ No ring conductor ground from the CPE ✦ No loop termination from the CPE.

Upon incoming seizure from the network, the FXS application module receives an A bit equal to 0. The FXS application module grounds the tip conductor towards the CPE. The reception of a B bit equal to 0 causes the FXS application module to send ring vo ltag e to the C PE. W hen the CPE te rminat es the loop, the FX S transmits both A and B signalling bits equal to 1 toward the network, terminates ringing, and enables the audio path.

Ground Start Call

Termination

(CPE end)

Ground Start Call Termination (by the network)

The CPE removes loop termination which causes the FXS application module to transmit the A signalling bit equal to a 0 and the B signalling bit equal to a 1. The network equipment returns an A signalling bit equal to 1. When the FXS receives the A signalling bit equal 1, it opens the tip conductor toward the CPE.

With both the CPE and the network in conversation mode and off hook, the FXS application module is providing −48 VDC on ring and ground on tip toward the CPE. The CPE is providing a loop closure toward the FXS application module. The FXS application module is transmitting A and B bits equal to 1 toward the network. The FXS application module is receiving A bits equal to 0 and B bits equal to 1 from the network.

When the network disconnects, the FXS application module receives an A bit equal to 1 (B is ignored) from the network. The FXS application module then

88 APPENDIX B: FXS VOICE APPLICATION MODULE

removes the ground from the tip toward the CPE and sends an A bit equal 0 and a B bit equal 1 toward the network. This is the idle state.

The FXS application module applies the tip ground and −48 VDC on the ring towards the CPE. The CPE tip and ring is open toward the FXS. The FXS transmits A and B signalling bits = 0 toward the network, receives an A bit = 0, and ignores the B bit from the network.

The FXS application module receives an A bit = 1 from the network and responds by transmitting both A and B signalling bits = 1 for 200 ms before returning A and B signalling bits = 0. The FXS applies ring voltage towards the CPE and transmits the ring back tone towards the network, coincident with the ring cadence.

The CPE terminates tip to ring in response to the ring voltage. The FXS recognizes the loop termination, removes ring voltage and ring back tone, enables the audio path, and transmits both A and B signalling bits = 1 towards the network.

The CPE removes the loop termination toward the FXS. The FXS transmits both A and B signalling bits = 0 toward the network. The network responds and the FXS receives an A signalling bit = 0 and ignores the B bit. This is the idle state.

From the network, the FXS receives an A signalling bit = 0 and ignores the B bit. The FXS responds by transmitting both A and B signalling bits = 0 toward the network and removing tip ground for 500 ms toward the CPE. The CPE removes tip to ring termination. This is the idle state.

Loop or Ground Start Signalling with Reverse Battery (MEGACOM)

The CPE applies termination between the tip and ring towards the FXS. The FXS transmits A and B signalling bits = 1 toward the network. The network returns a dial tone. The CPE then dials the number. The FXS receives an A signalling bit = 1 and ignores the B bit when the network answers.

This is the same as for Loop Start or Ground Start MEGACOM except that when a CPE-originated call connects, reverse battery is applied to the CPE tip and ring leads.

The FXS application module has the tip open and −48 VDC on the ring towards the CPE. The CPE has tip and ring open toward the FXS. The FXS transmits both A and B signalling bits = 0 toward the network, receives an A bit = 0, and ignores the B bit from the network.

The FXS application module receives an A bit = 1 and the B bit is ignored from the network. The change of state of the A bit causes the FXS application module to do the following.

✦ Set the B Transmit signalling bit to a 1 for approximately 200 ms and then returns

it to a 0.

✦ Send ring voltage with ring cadence toward the CPE. ✦ Send ring back tone towards the network, coincident with the ring cycle.

The CPE terminates the loop towards the FXS. The FXS ring trips on loop detect, depending on the ring cycle. The FXS transmits A and B bit = 0 towards the network, terminates the ring back tone and opens the audio path.

The CPE removes termination from the loop. The FXS transmits both A and B signalling bits = 0 toward the network. The network responds and the FXS receives an A bit = 0 and ignores the B bit. The FXS opens the tip toward the CPE and returns to the idle state.

From the network, the FXS receives an A signalling bit = 0 and ignores the B bit. The FXS opens the tip toward the CPE and transmits both A and B signalling bits = 0. The CPE responds to the open tip from the FXS by removing Loop Termination.

The CPE grounds the ring lead to the FXS application module. The FXS application module transmits both A and B bits = 1 toward the network. After 100 ms, the FXS then grounds the tip. The CPE terminates the tip to ring and removes ring ground. The FXS audio path is active.

The PLAR is used in pairs on opposite ends of network. The FXS application module transmits only two signalling states toward the network:

✦ Loop open from the CPE to the FXS application module, A and B signalling bits

equal 1,

✦ Loop closed from the CPE to the FXS application module, A and B signalling bits

equal 0 and opens the audio path.

90 APPENDIX B: FXS VOICE APPLICATION MODULE

The FXS application module responds only to the received A signalling bit and the B signalling bit is ignored. The FXS application module applies two seconds ON and four seconds OFF ringing to the CPE and ring back tone two seconds ON and four seconds OFF toward the network (only when the loop from the CPE is open and the receive A signalling bit changes from a 1 to a 0).

UVG UVG must use a Verilink FXO with the FXS in UVG mode. In UVG mode, the

FXO/FXS application modules automatically detect if they are in a loop start or ground start circuit and operate appropriately.

UVG with Reverse Battery

UVG with reverse battery must use a Verilink FXO with the FXS in UVG mode. In UVG mode, the FXO and FXS application modules automatically detect if they are in a loop start or ground start circuit and operate appropriately. With reverse battery enabled, a battery reversal from the CO is passed to the CPE.

DID/DNIS In DID and DNIS operation, an FXO application module in DPT mode is

connected to the CPE equipment. The CPE equipment must be capable of supplying loop current to the FXO application module. An FXS application module in DPO mode is connected to the CO and supplies loop current to the CO. Both DID and DNIS are inbound-only services (from the CO to the CPE).

Answer

The FXS application module provides ground to tip and −48V to ring towards the CO. The FXS transmits A and B signalling bits = 0 towards the network, receives an A bit = 0, and ignores the B bit.

The CO seizes the line by closing tip to ring. The FXS recognizes the loop closure and transmits A and B signalling bits = 1.

The CPE recognizes the seizure and responds with a wink. During the wink, the FXS receives an A bit = 1 and ignores the B bit. While the A bit = 1, the FXS outputs a battery reversal to tip and ring.

Ter m i n a te

Loop Start DNIS with Wink

After the wink, the CO passes digits to the CPE as DTMF tones or as pulses. DTMF tones are passed as voice frequency data to the CPE. Dial pulses are passed to the CPE by sending both A and B signalling bits = 0 during the break interval and by sending both A and B signalling bits = 1 during the make interval.

The CO terminates the call by opening the loop. The FXS transmits both A and B signalling bits = 0.

In Loop Start DNIS operation, an FXS application module in LS-DNIS mode is connected to the CPE equipment. Another FXS application module in DPO mode is connected to the CO and supplies loop current to the CO. The DNIS service is inbound only (from the CO to the CPE). Outbound calls are handled as MEGACOM or MEGACOM with Reverse Battery.
