DPRI 2922 Dual-Port ISDN Primary Rate Interface

The DPRI 2922 applicat ion module working in conjunction with an NCM 2000 controller mo dule provides your AS2000 system with critical network backup capability that includes ISDN PRI access.

NOTE: The ISDN capability of the DPRI 2922 application modul e is onl y

accessible through the NCM 2000 Controller Menu.

The DPRI accepts high-speed data from local area networks, host mainframes, and other types of data terminal equipment. The aggregate data rate from terminal equipment can be one of the following:

T1 Timeslots Data Rate

n = 1—23 or 1—24 dependin g on NFAS configuration

n × 56 kbit/s (up to 1.344 Mbit/s) (n = 1–

24) n × 64 kbit/s (up to 1.536 Mbit/s) (n = 1–

24)

Applications

In dial-backup mode, the DPRI 2922 is useful as an alternate ISDN route when regular T1 lines are unavailable. The DPRI 2922 also provides the ability to designate a reserve leased T1 as a backup.

Crosspoint Switch

The DPRI system carries data traffic onto a T1 transmission facility. Each port provides T1 transport bandwidth of n×56 kbit/s or

n×64 kbit/s trunks.

The DPRI system provides Advanced Automatic Protection Switching (AAPS) to an alternate T1 line using two hardware options:

•

DPRI with the CIM 29010, dual V.35 serial data ports

•

DPRI with the CIM 29011, dual RS-449/EIA-530 serial data ports

The DPRI system provides an alternate ISDN route for digital data traffic when the regular T1 line is unavailable.

The DPRI system provides an alternate T1 route for digital data traffic when the regular T1 line is unavailable.

The DPRI system provides flexibility for designing data paths to and from multiple AS2000 T1 modules across the backplane. Incoming and outg oing channels can be set up to send data traffic.

Drop, Insert, and Bypass Mode

Alarm Management

Advanced Programmable Architecture

1-2 Verilink DPRI 2922

The DPRI supports drop, insert, and bypass functionality via its crosspoint switch. Further, the drop, insert, and bypass configuration helps reduce the number of network (T1) links among different sites.

DPRI alarms are reported to the NCM. These alarms are viewed using the NCM Craft interface, Telnet, SNMP, or Node Manager.

All DPRI system hardware and software components can be independently up gra d ed wit h produ ct options and firmware upgrades. Additional mo dules can be added within a node to increase network channel capacity. CIMs and other modular components can be added, upgraded, or replaced independently.

ISDN Access

ISDN and Routine Management Tasks

Configuring the DPRI 2922 Via the NCM 2000 Craft Interface

For ISDN functionality, the DPRI 2922 Craft interface must be accessed from the NCM 2000 module. This may be done with a

direct cable connecti on from the NCM 2000 module front panel to an ASCII terminal or PC running a terminal emulator program, or using the NCM 2000’s Telnet capability.

To set up the dial-backup circuit feature, please see Chapter 2, “Creating an ISDN Dial-Backup Circuit”.

The following major functions are available through the Craft interface:

•

T1 port, data port, and timing parameter configuration

Logging On

•

Network and data port diagnostics

•

Performance, status, and alarm monitoring

•

Circuit building, editing, and viewing

In addition to the Craft interface, you can use Verilink’s Node Manager—a graphical user interface (GUI) management software package—to configure the DP R I module. For more information, see the Node Manager for Windows 95 User Manual.

Command Description Options

Line Coding: Use this option to choose Alternate Mark Inversion (AMI) or Bipolar Eight-Zero Substitution (B8ZS) as dictated by your T1 facility.

B8ZS is a protocol that replaces eight consecutive Zero bits with two intentional bipolar violations (BPVs) that are not counted as errors by the B8ZS equipment. B8ZS enables each DS0 to transmit at 64 kbit/s with unlimited zeros. This option overrides any selected network density enforcement.

AMI is a T1 signal in which successive Ones (pulses) alternate in polarity and in which Zeros (spaces) are of zero amplitude. AMI is the original T1 line format that does not support long strings of zeros. Normally, this option is used in conjunction with the network density enforcement option.

If the T1 facility experiences pattern sensitive errors or constant dribbling errors, verify that the unit is not mis-optioned for AMI. The intentional errors inserted by B8ZS equipment cannot be decoded by the AMI equipment.

AMI requires use of an ISDN inverted D-channel. Line Build Out: Line Build-Out is the signal strength used by the CSU and is

calculated by considering the length of the cable connecting the first line repeater and the CSU. It is the db loss inserted to compensate for transmitting levels to first repeaters w hen no network i nterface is in volved. Choose one of the following options:

0 db: if the repeater is between 2000 and 3000 feet from the CSU, or if you are using a network int erface unit (smart jack) used by m os t pho n e companies.

-7.5 db: if the repeater is between 1000 and 1999 feet from the CSU.

This is the recommended option for IS DN.

1) AMI

2) B8ZS

1) 0 db

2) -7.5 db

3) -15 db

4) -22.5 db

-15 db: if the repeater is between 250 and 999 feet from the CSU.

-22.5 db: if the repeater is between 0 and 249 feet from the CSU. Network Density: Use this option to specify the type of network density

enforcement to use with PRI line coding. Digital transmissions over public switched telephone network lines cannot support long strings of zeros (repeaters and clocking devices lose synchronization). Therefore, the density algorithms ensure that a minimum pulse density is met to ensure stable system timing.

Choose one of the following if using 64K AMI. Note that these options are ignored with B8ZS line code:

None: does not ins ert a o ne.

Also recommended for ISDN capability.

80 zeros: inserts a one i nto ever y stri ng of more th an 8 0 cons ecuti ve zeros. 15 zeros: inserts a one i nto ever y stri ng of more th an 1 5 cons ecuti ve zeros.

12.5% & 80 zeros: inserts a one into every string of eight or more consecutive zeros when the avera ge d ensity of ones fal l below 12 .5 % or if there are more than 80 consecutive zeros.

TR 62411: inserts a one in to ev ery string of more than 15 consecutive zeros or when there are less than a minimum number of N ones in every window of 8(N+1) data bits (12.5%). N can be any value from 1 to 23. This option is the same as 12.5% + 15 zeros.

DPRI to be remotely put into a line loopback.

Use this menu to determine the transmit timing source of the DPRI modules. If the DPRI module derives its timing from another card in the shelf, enter the slot of the module to be the timing source. This includes the option of setting the DPRI as the timing source for the shelf.

Select primary, secondary, and tertiary timing sources. The secondary and tertiary timing sources provide a backup for the primary timing source. The Auto Restore option determines which timing source is used when the primary timing source fails, restores, and then remains viable for a period of 60 seconds.

If the primary source fails, the secondary source becomes the timing source. When the primary source recovers and the Auto Restore option is set to “Yes”, the primary source resumes service as the DPRI module’s timing source. If the Auto Restore option is set to “No”, the secondary source remains the timing source until you manually reconfigure the primary source, or set its Auto Restore option to “Yes”.

NOTE: For ISDN, the network ALWAYS supplies a clock that MUST be the

Clock Option: Use this option to select one of the following: Serial Transmit (ST): In this mode, the normal non-inverted phase of the Serial

Clock Transmit (SCT) is used to clock data from the DTE into the DPRI module’s data port transmit buffer. This is the default setting.

Inverted Serial Transmit (INV ST): In this mode, the inverted phase of the SCT is used to clock data from the DTE into the DPRI module’s data port transmit buffer—when compensating for phase delays (caused by using long cables) an d when the far end is receiving bit errors. TT is a better alternative.

Terminal Timing (TT): In this mode, Serial Clock Transmit Extension (SCTE) is used to clock data from the DTE into the DPRI module’s data port transmit buffer. Normally, this clock is looped by the DTE from the SCT signal. It is the preferred timing method because the transmit clock and data are alw ays in sync regardless of cable length. Unfortunately, this signal is not provided by all DTE equipment. Set this option in tail-circuit timing applications (when the data port receives timing from another circuit).

Control Line Indicator (On E1 networks only): Use this option in the data port interface for flow control. LOW indicates that the port’s signal follows the DTE signal. HIGH indicates that the port’s signal is always on.

In Figure 3-8, the parameters enclosed in the grey box are port status listings. The first four lines show the state of the incoming handshake leads. “HIGH” means incoming handshake signals are detected on that lead, and “LOW” means no handshake signaling is detected. In DCE mode, if the TM lead is “HIGH,” the data port is in test mode, whereas in DTE mode, it indicates the state of the equipment. DPL Loopback shows whether a data port loopback has been enabled or disabled (in the Data Port Diagnostics Menu). If a test pattern has been enabled in the Data Port Diagnostics Menu, “QRSS” (Quasi-Random Signal Sequence) is displayed in this field and the number of errors detected by the test is displayed by the Error Counter.

Cyclic Redundancy Check (CRC): An error-checking algorithm performed on data transmissions. On a frame-by-frame basis, a numerical value is derived from the data in the bit stream at o ne end of trans mission. When each frame reaches the receive end, th e cy clic redundancy check is calculated again and compared with the value generated by the transmit-side data. Discrepancies can indicate one or more transmission errors. This counter is only available in ESF mode.

Command Description

Errored Seconds (ES): A second with one or more AIS, LOS, or LOF defects. Unavailable Seconds (UAS): Counted for ever y sec ond in which an Unavailable Signal State

occurs with the onset of 10 contiguous SES errors. It is also defined as the number of seconds a service is unavailab l e due to a Lo ss of Fra me ( L OF ) co ndition. The UAS condition is stopped when the failure condition clears.

Bursty Seconds (BES): A second having between 2 and 319 CRC-6 (Cyclical Redundancy Check error events.

Severely Errored Seconds (SES): This error counts one se cond intervals with an AIS or CRC error.

Loss of Signal (LOS) Seconds: A second during which the DPRI is in a Loss of Signal state. LOS is declared upon detecting 175 consecutive zeros, it is cleared with the receipt of the next 1 bit.

Severely Errored Framing (SE F) Se conds: Those seconds in which two or more framing bit errors occur withi n a 3-m illis econd p eriod . In ESF mod e, this inte rval may o r may n ot co inci de with an ESF multiframe.

Loss-of-Frame (LOF) Seconds: An LOF alarm is declared when a 3 -second interval of

continuous Out-Of-Frame (O OF) or Loss-Of-Signal (LOS) state is detected. If at least 10 seconds elapse without an LOS or LOF error, the LOF alarm is cl eared.

Out-of-Frame (OOF) Seconds: A condition when any three of four consecutive frame bits

received from the T1 line are incorrect.

Alarm Indication Signal (AIS) Seconds: A count of one-second intervals containing one or more

AIS defects. AIS is an unframed All-Ones bit pattern that indicates an alarm condition exists upstream in a circuit leading to the downstream equipment. This is also called an All-Ones Keep-Alive or Blue Alarm Signal. An AIS defect is declared when there are 3 or fewer zeros in 512 bit times and there is an LOF defect. It is cleared when there are 3 or more zeros in two frames or the LOF defect no longer exists.

Controlled Slip Seconds: This error indicates that in a one second interval one or more slip

events occurred. An accurate count of controlled slips that occur can only be made at the terminating network element where the slips take place.

The current version of the firmware does not support this feature.

Loss of Frame Counts: An accumulation of the number of times a Loss-Of-Frame alarm is

declared.

AIS/SEF Seconds: Displays information on the AIS and SEF errors. AIS: An unframed All-Ones bit pattern that indicates that an alarm condition exists upstream

in a circuit leading to the downstream equipment. Th is is also calle d an All-Ones Ke ep-Alive or Blue Alarm Signal.

SEF: The seconds in which two or more framing bit errors occur within a 3-millisecond period. In ESF mode, this interval may or may not coincide with an ESF multiframe.

Errored Seconds Type A: This error occurs when one Code Violation Path (CV-P) error and no

AIS defects occur in a second. Cont rolled Slips a re not included in this parameter.

Frame Bit Error (FE): An error in the received framing bit pattern and the number of whole

seconds that a framing bit error has occurred.

-6

Degraded Minutes (DM): This error occurs when the Bit Error Rate (BER) threshold of 10

exceeded in a 60 second p eri od.

Error Free Seconds: A second with no detected error s.

Interpreting Alarms

Troubleshooting

Controller card(s) poll the various modules for alarms. If alarm reporting is enable d for the node and for the module(s), the node controller card retrieves and sends the alarm to Access Manager 2000, Node Manager 2000, or an SNMP agent. Various alarms can also be set up via the NCM 2000 module to trigger the dial backup or backup T1 as part of the Advanced Automatic Protection Switching feature.

An alarm list is provided under th e alarms displays of the various options of AM2000, NM2000, SNMP, or ASCII.

Alarms can also be automatically sent to a specified printer by setting up the printer address in the various management utilities menus.

The alarm buffer displays the following information about alarms (This information may vary depending on the controller module and management method used):

What To Do About Alarms

Some alarms clear after the user-configured timeout has expired. Other alarms require co rrective action.

•

If an alarm has been cleared, no other action is required.

•

If there is a loopback present, unless you are intentionally testing, remove the loopback. (Only if the loopback is from your end. If the loop was initiated by your network service provider, check with their test facility before taking down the loop.)

•

For an LOF, you may have a telco or module problem. To test, do an RLB. If there is no LOF indicated by the test, the problem is with the telco.

•

For an LOS, check your router cables, power, and ports.

•

For a power-up self-test failure, reseat the module a few times to see if it will power up and pass the self test. If it does not pass after repeated self tests, replace the module.

Troubleshooting

Alarm Records

Every alarm record that displays is “active” in the database until you do something about it. Do the following with the alarm records:

•

Deactivating alarm records is a database management function. As long as an alarm is active, you can view it onscreen, using the one of the management options on the ASCII interface, AM2000, or Node Manager 2000. When you deactivate an alarm, it’s still in the database, but not viewable on screen. Deactivated alarms can be archived, printed, or deleted.

•

Archiving an alarm record stores it to a disk file you specify.

•

Printing an alarm record p rints a copy of all active and deactivated alarms.

•

Deleting an alarm record re moves it from the database. To delete an alarm, first d eactivate it.

Alarm List

Table 4-1 Alarms

Alarm Classification/

Alarm Type Description

Fault conditions can result in critical, major, or minor alarms. In addition, a fault condition can also result in a Carrier Failure Alarm (CFA).

Critical Alarms

Carrier Failur e Alarm (CF A)

Major Alarms

Alarm Type Description

Loss of Signal (LOS)

A critical alarm indicates the node or node components ha ve failed. Only the loss-of-clock (LOC) error condition triggers a critical alarm. This error causes the system clock to fail and prevents data from being transmitted.

Loss-of-clock causes the System LED to flash red. It causes a major alarm and activates the relay contacts on the rear connector panel of the CIM.

A carrier failure alarm (CFA) is activated w hen certain major alarm error conditions occur, causing the port to disrupt traffic along the line. When the CFA is activated, the line is not useable—preset by the user—for 2 to 60 seconds. All traffic is re m oved from the line. The alarm re mains active until the port is reconfigured.

A major alarm fault condition seriously affects performance. It prevents data from being reliably transmitted across the circuit. When a major alarm is declared, the module sends a message to the ASC II interface and Node Manager, lights the appropriate LED indicator, and trips the alarm relay. The following error conditions must persist for at least one second for a major alarm to be declared.

This condition occurs when the network signal is absent, and exceeds a predefined loss-of-signal threshold. An LOS alarm on a network line is declared when more than 175 consecutive zeros are detected on input to the receiving equipment. An LOS after o ne continuous sec o nd causes a major alarm and activates the relay contacts on the rear connector panel of the CIM.

This alarm activates the CFA if the LOS is active from 2 to 45 seconds (as defined by the user).

Alarm Indication Signal (AIS)

Loss of Frame (LOF) (T1 Only)

4-4 Verilink DPRI 2922

Using an unframed ALL-ONEs bit pattern, an AIS alarm indicates that an alarm condition exists upstream in a circuit leading to the downstream equipment. This is also called an ALL-ONEs Keep-Alive or Red Alarm Signal. An AIS defect is declared when there are 3 or fewer zeros in 512 bit times and an LOF defect. It is cleared when there are 3 or more zeros in two frames or the LOF defect no longer exist s .

This alarm activates the CFA if the AIS is active from 2 to 45 seconds (as defined by the user).

This alarm is declared when a 3-second interval of continuous Out-Of-Frame (OOF) or Loss-Of-Signal (LOS) state is detected. An LOF alarm is cleared when at least 10 seconds of continuous non-LOS or non-LOF condition exists.

This alarm activates the CFA if the LOF is active from 2 to 45 seconds (as defined by the user).

Alarm Classification/

Alarm Type Description

Troubleshooting

Loss of Frame Alignment (E1 Only)

Frame Alignment Signal Error Rate (FASER) (E1 Only)

Loss of TS16 Multiframe Alignment (LOMA) (E1 Only)

This condition occurs when three consecutive in-error frame alignment signals (words) are received, or when Bit 2 in a frame containing the nonframe alignment signal (N FAS wor d ) is received in error three consecutive times.

The condition clears when the following even ts are satisfied:

• The frame alignment signal is detected in frame N.

• The non-frame alignment signal 1 is detected in frame N+1.

• The frame alignment signal is detected in frame N+ 2. Loss-of-frame alignment (LOFA) after one continuous second causes a major

alarm and activates the relay contacts on the rear connector panel of the CIM. This alarm activates the CFA if the LOFA is active from 2 to 45 seconds (as

defined by the user). This alarm indicates that the FAS error rate exceeds a user-selectable

threshold of 10

-3

or 10-6 for at least four seconds. This user-selectable al arm can be designated as a major or minor alarm and activates the relay contacts on the rear connector panel of the CIM.

This alarm activates the CFA if the FASER is active from 12 to 60 seconds (as defined by the user).

This condition occurs when the module c anno t find the mul tiframe align ment signal (MAS) pattern on TS16 when enabled for CAS signaling.

This alarm activates the CFA if the LOMA is active from 2 to 45 seconds (as defined by the user).

Minor Alarms

Minor alarm fault c ond itio ns do not affec t traf fi c alo ng the network line . They generate a minor alarm.

Alarm Type Description

Power Supply

In redundant power supply configurations, this alarm indicates that one of the redundant power supplies has failed or has been removed from the shelf.

Missing Remote

Alarm Indication (RAI)

RAI. This alarm indicates that the remote end is in a state of alarm. A Remote Alarm or Remote Alarm Indication is the alarm a receiving channel bank or multiplexer sends to the other end of the circuit when it detects a Loss Of Signal or Loss Of Frame. There is a 2- to 3-second integration period upon detection of LOS or LOF before a Yellow Alarm is sent to the far-end equipment. This condition is also referred to as a Yellow Alarm.

Bipolar Violation (BPV) Threshold

Severely Errored Second (SES)

A violation of the T1 bipolar AMI transmission pattern requi ri ng successive Ones (pulses) to be transmitted as pulses of opposite polarities. A BPV alar m indicates transmission errors. However, B8ZS patterns contain intentional BPVs that are not counted as errors.

15 min. Threshold/ SES 24 hr. Threshold—An SES alarm is declared when 320 or more ESF error events occur within one seco nd, o r when an OOF (Out- O fFrame Second) occurs. An SES is a one-second period containing greater than 30% errored blocks (more than 1 errored bit) or at least one Severely Disturbed Period (SDP).

Bit Error Rate (BER) Threshold

The Bit Error Rate is the ratio of the number of bit errors received to the total number of bits transmitted in a given interval. The BER threshold indicates the level above which a CSU alarm is gen era ted an d repo rted .
