Chapter 4, E1 version administrative, configuration, performance and diagnostic functions.

Where the Verilink ASCII terminal interface (Craft interface) is discussed, this manual assumes the module is used with an NCM 2000 Node Controller Mo dule. The menus and options will be similar when the module is accessed directly via the onboard port.

The DIDCSU can operate as a standalone module or as part of an NCM 2000 node. Ci rcuits ma y be bui lt between ports on DIDCSUs in the same shelf only when an NCM is present. In the absence of an NCM, the DIDCSU can be the shelf controller.

The DIDCSU 2912 supports a number of features and modes of operation.

The DIDCSU 2912 multiplexes digital data and video tr affic onto a T1 or E1 transmission facility. Each port provides T1/E1 bandwidth of n × 56 kbit/s or n × 64 kbit/s trunks.

Additional DIDCSU modules can be added within a node to increase T1/E1 channel cap acity. CIMs and othe r modular componen ts ca n be added, upgraded, or replaced independently.

The DIDCSU 2912 accepts high-speed data from routers, front end processors, video codecs and other types of data terminal equipment. It multiplexes this data into some number of 56 kbi t/ s or 64 kbit/s DS0 timeslots an d ei ther passes them out a network port, or with an NCM as node controller only, onto a shelf midplane for connection to another module.

CSU/DSU

The DIDCSU 2912 can be used in a simple configuration in which it functions as two T1 or E1 CSU/DSU units. Data from the firs t data port can be mapped to th e first network port, whil e data from the second data port is mapped to the second network port. Except for a common transmit clock source, these two CSU/DSU functions are independent of each other

Drop, Insert, and Bypass Mode

The DIDCSU 2912 supports drop, insert, and bypass functionality via a crosspoint switch.

The drop, insert, and bypass configuration reduces the number of network link s be tween differe n t s i te s . T h e three interco n n e cte d sites in Figure 1-1 can have certain applications, such as video conferencing, which are used only occasionally. These sites can allocate a specific bandwidth of the T1/E1 line for the weekly onehour video conference, and at other times, use the bandwidth for other purposes.

DIDCSU 2912 Overview

The DIDCSU 2912 does the necessary cross-connections to ensure that the local area network signal from Building 1 terminates (or drops) at Buil ding 2, the vide o circuit is added (inserted), and the outgoing data stream is sent on to Building 3.

1. Video data from Building 1 is destined for Building 3 but, because there is no direct connection, is sent to Building 2 over a network line. The node at Building 2 cross-connect s the video data to timeslots on the network line that links Building 2 and Building 3. The video circuit arrives at Building 3. (Bypass)

2. LAN A in Building 1 uses timeslots on the network line to Building 2 for transmitting and receiving data from LAN B. (Drop)

3. LAN C in Building 2 uses timeslots on the network line to Building 3 for transmitting and receiving data from LAN D. (Insert)

DIDCSU 2912 Quick Set-Up

This chapter is divided into two main sections. The first section provides step-by-step procedures for installing your DIDCSU 2912 module on a T1 circuit. The second portion of this chapter provides step-by-step procedures for an E1 installation.

This quick configuration guide makes the following assumptions:

•

You are installing the DIDCSU 2912 in a dual-line shelf with an NCM 2000 module.

•

You are connecting two T1 facilities—one an FT1 using 12 DS0s, the other a full T1 with 24 DS0s—to the two network ports of the DIDCSU 2912.

•

The full T1 connects to Net Port 1 and all of the timeslots are mapped to Data Port 1, the fractional T1 is connected to Net Port 2 and the first 12 DS0s are mapped to Data Port 2.

Connect to Craft Port

•

The NCM 2000 controller module is in slot 1 and the DIDCSU is in slot 2.

This quick configuration guide makes the following assumptions:

•

You are installing the DIDCSU 2912 in a dual-line shelf with an NCM 2000 module .

•

You are connecting two E1 facilities—one a fractional E1 using 15 DS0s, the other a full E1 with 30 DS0s—to the two network ports of the DIDCSU 2912.

•

The full E1 connects to Net Port 1 and all of the timeslots are mapped to Data Port 1, the fractional E1 is co nnected to Net Port 2 and the first 15 DS0s are mapped to Data Port 2.

•

The NCM 2000 controller module is in slot 1 and the DIDCSU is in slot 2.

DIDCSU T1 Version

This chapter describes how to configure and adm in is te r the DIDCSU 2912 T1 parameter s us i ng the NCM 2000 Craft interface. For E1 circuits, refer to Chapte r 4, “

The following major functions are available through the Craft interface:

•

Administering nodes

•

Configuring the T1 ports, data ports, and timing parameters

•

Performing diagnostics on network and data ports

•

Evaluating perf or ma n ce an d s ta t us

•

Monitoring alarms

•

Building, editing, and viewing circuit information

In addition to the NCM Craft terminal interface, yo u can use Verilink’s Node Manager—an interactive graphical user interface (GUI) management soft ware package—to co nfigure a node equip ped with an NCM module. For more information, see the

”.

Connecting to the Node

Use the following method to connect to the node which contains the DIDCSU 2912.

Cable Connection

Connect the modular (RJ-11) end of the Craft cable (P/N 458102119-008) to the port labeled controller module. Connect the other end of the Craft cable to your PC or terminal.

NOTE:

LOCAL

on the front panel of the NCM

This manual assumes the DIDCSU 2912 is part of a node of Verilink modu les which is manag e d by an N CM 20 00 . Th e DIDCSU 2912 can also be used as a standalon e module. In that case the craft cable is connected directly to the DIDCSU module. When a DI DCSU is part o f a n ode tha t is managed by an NCM, do not connec t directly to the DIDC SU module local port for any reason other than changing the ACP bus selection, if required.

R Reset Card—Use this option to re-initialize the DIDCSU. Code is not

copied from either partition. Instead, the counters are all reset to zero. Do not use Reset Card to test newly downloaded firmware, use Switchover Once instead.

Y Switchover Once—Use this option for testing new firmware versions.

This option switches the module from partition A to B or vice versa. The partition selected is not set as the default power-up partition.

I Change Site Name—Use this option to specify the site name for the

DIDCSU. All reports will contain this information, which—in case of problems—will help identify the problem location.

U Cle ar Card Configuration—Use only with caut ion! This option resets

all configurable optio ns in the DID CSU to their ori ginal, facto ry default values. It may cause a loss of communication with the module because the ACP bus option is reset as well.

Do not use this option while managing a site remotely unless a technician is onsite and available to re-assign the ACP bus (if needed).

Table 3-8 Data Port Configuration Menu Parameters

Command Description Options

In In Service: Use this option to place the port in service. Yes or No

(Y/N)

Mn Data Port Mode: Use this option to select one of the following:

• Data Terminal Equipment (DTE): if the equipment connected to the DIDCSU is a DCE, then the Data Port Mode is DTE. Mostly used with tail circuits. However, using a crossover cable is a better option. See the manual

• Data Circuit-terminating Equipment (DCE): if the equipment connected to the DIDCSU is a DTE, then the Data Port Mode is DCE. DCE is the default setting and is by far the most commonly used.

Cn Clock Option: Use this option to select one of the following:

• Serial Transmit (ST): In this mode, the DIDCSU data port samples the Transmit Data lead during the negative-going transition of the Transmit Clock signal provided by the DIDCSU. This is the default setting.

• Inverted Serial Transmit (INV ST): In this mode, the DIDCSU data port samples the Transmit Data lead during the positive-going tran sition of the Transmit Clock signa l provid ed by the D IDC SU. This is usef ul when compensating for phase delays (caused by usin g l ong cables) and when the far end is receiving bit errors reported by a higher level protocol-but not the far CSU/DSU.

• Terminal Timing (TT): In this mode, the optional third pair of clock leads (Serial Clock Transmit Extension—SCTE in V.35, Terminal Timing—TT in RS-422) is used to clock data from the DTE into the DIDCSU module’s data port transmit buffer. Normally, this clock is looped by the DTE from the Transmit Clock signal. It is the preferred timing method because the transmit clock and data are always in sync regardless of cable length. Unfortunately, this signal is not provided by all DTE equipment. Select this option in tail-circuit-timing applications (when the data po rt receives timing from another circuit).

On Enable Loss-of-Signal (LOS) Detection: Indicates if the cable is plugged

into the data port. If set to DTR, an alarm is generated if the cable is unplugged, or if the DTE equipment drops the handshake lead. In DCE port mode, this is a DSR lead.

Ln Control Lead Mode: If Control Lead Mode is Auto, then CTS (Clear To

Send) is returned when the D TE presents RTS(Request To Send) and DSR(Data Set Ready) is returned when the DTE asserts DTR (Data Terminal Ready).

• Cyclic Redundancy Check (CRC): An error-ch ecking algorithm perform ed on data transmissions. On a frame-by-fra me ba sis, a numerical value is derived from the data in the bit stream at one end of tr a nsm iss ion. Wh en each frame reaches th e r ec eive end, the cyclic redundancy check is calculated again and compared with the val ue generated by the transmit-side data. Discrepancies can indicate one or more transmission errors. This counter is only available in ESF mode.

Errored Seconds (ES): A second with one or more AIS, LOS, or LOF defects. Unavailable Second s (UAS): Counted for every second in which an Unavail able Signal State

occurs with the onset of 10 contiguous SES errors. It is also defined as the number of seconds a service is unavailable due to a Loss-of-Frame (LOF) condition. The UAS condition is stopped when the failure cond ition clears.

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

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

Loss-of-Signal (LOS) Seconds: A second during which the DIDCSU 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 (SEF) Seconds: Those 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.

Loss-of-Frame (LOF) Seconds: An LOF alarm is declared when a 3-second interval of continuous Out-Of-Frame (OOF) or Loss-of-Signal (LOS) state is detected. If at least 10 seconds elapse without an LOS or LOF err o r, the LOF alarm is cleared.

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 unf r a med all-ones bit pattern that indica tes an alarm condit io n exists upstream in a circuit leading to the down st r e a m equ ip m en t . Th is is al so called an All-Ones Keep- Ali v e o r Bl ue Ala rm Signal (as sent) or a Red Ala rm (a s rec e ived). 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 er ror indicate s that in a one-se cond inter val one or more sli p events occurred. An accu rate co unt of c ont rolled s lips ca n on ly be made a t the te rmina ting 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 in formation 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. This is also ca lled an AllOnes Keep-Alive or Blue Alarm Sig nal (as sent) or a Red Alarm (as received).

• 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. Controlled Slips are 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 occurre d.

Degraded Minutes (DM): This error occurs when the Bit E rror Rate (BER) thre shold of 10 exceeded in a 60 second period.

Error-Free Seconds: A second with no detected errors. Reset Registers: Use this option to clear out all counts and reset all registers to zero for a

DIDCSU E1 Version

This chapter describes how to configure and adm in is te r the DIDCSU 2912 E1 parameters using the NCM 2000 Craft interface. For T1 circuits, refer to Ch apter 3, “

The following major functions are available through the Craft interface:

•

Administering nodes

•

Configuring the E1 ports, data ports, and timing parameters

•

Performing diagnostics on network and data ports

•

Evaluating perf or ma n ce an d s ta t us

•

Monitoring alarms

•

Building, editing, and viewing circuit information

In addition to the NCM Craft terminal interface, yo u can use Verilink’s Node Manager—an interactive graphical user interface (GUI) management soft ware package—to co nfigure a node equip ped with an NCM module. For more information, see the

User Manual

.

DIDCSU T1 Version

Node Manager

”.

Connecting to the Node

Use the following method to connect to the node which contains the DIDCSU 2912.

Cable Connection

Connect the modular (RJ-11) end of the Craft cable (P/N 458102119-008) to the port labeled controller module. Connect the other end of the Craft cable to your PC or terminal.

NOTE:

LOCAL

on the front panel of the NCM

This manual assumes the DIDCSU 2912 is part of a node of Verilink modu les which is manag e d by an N CM 20 00 . Th e DIDCSU 2912 can also be used as a standalon e module. In that case the craft cable is connected directly to the DIDCSU module. When a DI DCSU is part o f a n ode tha t is managed by an NCM, do not connec t directly to the DIDC SU module local port for any reason other than changing the ACP bus selection, if required.

En CRC-4: Cyclic Redundancy Check (CRC-4) is an error-checking

algorithm performed on digital transmissions. On a frame-by-fr ame

Yes or No

(Y/N) basis, a numerical value is derived from the data in the bit stream at one end of transmission. When each fra me reaches the receive end , the cyclic redundancy check is calculated ag ain and compared with the value generated by the transmit-side data. Discrepancies usually indicate one or more transmission errors.

indicating an E1 port has exceeded the Loss-of-Frame and the Loss-of-

Yes or No

(Y/N) Signal seconds threshold set in the Net Port Alarm Configuration Menu. When enabled, an alar m is generated at the node and an Alarm Indication Signal (A IS) is sent down stream to the other node.

occurs in bits 2-8 of the FAS frame and bit 2 of the non-FAS frame. A minor FASE alarm is indicated by an amber light on the network LED.

A major FASE alarm is indicated by a red light on the network LED, and the alarm relay is enabled.

Mn Frame Mode: Used to set the way timeslots 0 and 16 will be handled by

the DIDCSU. CAS—Timeslot 0 is used for framing and timeslot 16 carries switched

telephone call setup and supervision information according to the

CCS—Timeslot 0 is used for framing and timeslot 16 carries switched telephone call setup and supervision information according to the Common Channel Signalling standard. This selection may apply if some or all of the timeslots are used for PBX based voice traffic.

31 Channel—Timeslot 0 is used for framing and timeslot 16 is available for data traffic as are the remaining 30 timeslots.

Unframed—No timeslot is used for framing or voice channel signalling. This will not be a valid selection for most E1 facilities. Network timing cannot be used in this mo d e.

channel to receive and transmit remote configuration and diagnostic information. The channel must be enabled on both ends of the E1. You must designate the timeslot also (see below) only if inband is enabled.

The unit will not activate if timeslot 0 is chosen as the default. This feature can be used to extend NCM management to a DIDCSU at

the far end of an E1 circuit.

Note that the lead options swap inputs and outputs between the DCE or DTE data port modes.

There are three controllable diagnostic leads at the data port (which are set up via the

In Figure 4-8, the parameters listed in the dashed box are port status listings. The first four lines show the state of the incoming handshake leads. ON means incoming handshake signals are detected on that lead, and OFF means no handshake signaling is detected. In DCE mode, i f the TM lead is ON, it indicates that the data port is in test mode, whe r eas in DTE mode, it indicates the state of the equipment.
