12 1-4 Introducing the DV-45 system DV-45 units A DV-45 DV- unit is a plug-in module that multiplexes and demultiplexes three DS3 signals to one SONET (155 Mb/s) fiber signal. An DV- unit occupies two slot positions in a DV-45 shelf. DS3 signals are connected by BNC connectors located at the rear of the DV-45 shelf and fiber optic connections are made at the front of the unit. Additional information For additional information on the DV-45 Digital Video Codec product, refer to the DV-45 Reference Manual, PEC NT2H7902. Digital Video Codec DV FWP Standard

13 2-1 DV- unit description 2- This chapter describes the DV-45 DV- unit purpose, features, functions, and interface connections. A DV- unit is a plug-in module used to multiplex and demultiplex up to three DS3 signals to one SONET fiber signal. The unit occupies two slot positions in a DV-45 shelf (slots 0 and 1, 2 and 3, 4 and 5, or 6 and 7). The three DS3 signals are connected by BNC connectors located at the rear of the DV-45 shelf. The fiber optic signals are connected to intermediate-reach or long-reach optical modules using ferrule (FC), straight (ST), or subscriber (SC) connectors located at the front of the DV- unit. The long-reach optical modules have a greater output power and greater input sensitivity. The two types of optical module and three types of connector lead to six types of DV- unit. The six types of DV- unit, identified by their Nortel product engineering code (PEC), are: PEC NT2H08AB NT2H08AC NT2H08AD NT2H08BB NT2H08BC NT2H08BD Description DV- unit, long reach, FC connector DV- unit, long reach, ST connector DV- unit, long reach, SC connector DV- unit, intermediate reach, FC connector DV- unit, intermediate reach, ST connector DV- unit, intermediate reach, SC connector DV- Unit Reference Manual FWP Standard

19 3-1 Alarm indications 3- This chapter lists the DV- unit alarms, the conditions that initiate them, the telemetry byte-oriented serial (TBOS) mappings, and alarm interpretation. Overview The central processing unit (CPU) of a DV- unit detects and diagnoses alarms. The CPU routes alarms to the unit s faceplate and the internal maintenance bus (M-bus) on the DV-45 shelf backplane. A DV-45 maintenance control unit (MCU) collects alarms from the M-bus, classifies them as major or minor alarms, and routes them to parallel and serial (TBOS) alarm ports at the rear of the DV-45 shelf. Various conventions are used to define signal transmit (Tx) and receive (Rx) directions; the convention used within this chapter is illustrated in Figure 3-1. Figure 3-1 Signal convention DS3 signals Rx Tx signals Tx DV- unit Rx Rx = receive Tx = transmit Alarm and status reporting A DV- card has two modes of operation bidirectional or unidirectional. These modes determine alarm and status reporting. The line and STS-DS3 transmit (Tx) and receive (Rx) interfaces may be equipped or unequipped. The DS3 line build out (LBO) may be set to IN or OUT using switches or TBOS commands. The system clock may be set to Loop timed or Freerun mode. DV- Unit Reference Manual FWP Standard

20 3-2 Alarm indications Some TBOS control points function as both status indicators and command points. When used as a command point, the operator can operate a momentary latch from TBOS and override the switch settings. The state of the line, STS path, DS3 interface, LBO, and system clock are set by switch settings on the DV- unit (see Setting DV- unit options on page 8-7) and may be overwritten by TBOS command points set by the MCU. STS path unequipped and DS3 alarm indication signal (AIS) are automatically inserted by the software on unequipped channels. Hardware status is reported using alarm points and may be accessed through the MCU E2A1, RS-422, serial alarm port using a TBOS digital alarm scanner. Most hardware faults are detected by self-checking circuitry. Alarm and status information is reported by the software as equipment or facility alarms. The CPU is reset whenever a software failure is detected. Remote alarm and status reporting is not supported, so all alarm and status information is only reported locally. Alarms on channels provisioned as unequipped are not reported. Note: For TBOS 1.0, the DS3-x Fac. Lpb control points function as both status indication and command points. For TBOS 2.0, the STS-x Tx Eqp., STS-x Rx Eqp., DS3-x Fac. Lpd Rq, DS3-x LBO, and Loop Time all function as both status indication and command points. Faceplate alarm indicators Equipment and facility alarms are indicated using colored light-emitting diodes (LED) on the faceplate. Refer to Table 3-1 for each alarm indication and its associated LED. Refer to Figure 3-2 for the location of each LED on the faceplate. To eliminate related alarm indications; lower-level alarms are masked when associated higher-level alarms are generated (see Figure 3-3). Table 3-1 DV- unit faceplate LED alarm indicators LED Alarm Indication (Yellow) This LED indicates one or more facility alarms: LOS (loss of signal); LOF (loss of frame); Line AIS (alarm indication signal); Line FERF (far-end receive fault); Line degrade (B2 BIP-8); Section degrade (B1 BIP-8); Signal degrade STS/ (Yellow) These LEDs indicate one or more of the following STS1 path or DS3 facility alarms (alarms on unequipped channels are not STS/DS3-2 (Yellow) reported): STS AIS (alarm indication signal) path detect; STS STS/DS3-3 (Yellow) yellow detect; STS path degrade; STS Rx path unequipped; STS signal label mismatch; DS3 Tx loss of signal; Tx BCV (bipolar code violation); DS3 Tx/Rx frame loss; DS3 Tx/Rx AIS (alarm indication signal); DS3 Tx/Rx degrade ON (Green) FAIL (Red) This LED indicates that the unit is active and functioning correctly This LED indicates one or more of the following equipment failure alarms: battery A and B; power; mapper (R96); TOP; Muldem; clock module; PAL chip; optics Digital Video Codec DV FWP Standard

23 Alarm indications 3-5 Alarm port indicators All equipment and facility alarms routed to the maintenance bus (M-bus) on the DV-45 shelf backplane are gathered by the MCU, classified as major or minor, and routed to parallel (relay closure) and serial (E2A TBOS) alarm ports at the rear of the DV-45 shelf (refer to Figure 3-4). Visual and audible indicators can be connected to the parallel, relay contact, port. A TBOS digital alarm scanner can be connected to the serial E2A1 RS-422 port. To determine alarm causes, see Interpreting alarms and status indicators on page 3-9. Note: Orderwire capability is not supported.

24 3-6 Alarm indications Parallel alarm port The parallel port provides normally open (NO) and normally closed (NC) relay connections for major and minor visual (for example, lamp) and audible (for example, buzzer) indicators. All major and minor alarm indicators are activated upon power failure. An external alarm cutoff (ACO) connection is provided so that audible alarm indicators can be silenced (see Figure 3-4). Serial alarm port The serial alarm port is an industry standard E2A, RS-422, port (see Figure 3-4) which can represent up to 512 alarm points (each point is represented by one bit). The alarm points can be accessed through the port eight bits at a time by a TBOS digital alarm scanner. This section assumes you are familiar with TBOS; for a full description, see Alarms and Surveillance, , within the DV-45 Reference Manual, PEC NT2H7902. Alarm points are used to represent the same alarms as those routed to the LED faceplate indicators on the DV- unit. All alarm points are mapped to bits and bytes according to the DV-45 shelf position of the DV- unit. A DV-45 MCU can be optioned for TBOS 1.0 or TBOS 2.0 E2A mappings and display addresses (see Figure 8-10 on page 8-16). For TBOS 1.0 mappings, refer to Table 3-2. For TBOS 2.0 mappings, refer to Table 3-3, Table 3-4, Table 3-5, and Table 3-6; for TBOS 2.0, each DV- unit occupies an entire display.

29 4-1 DV- unit applications 4- DV- units can be used in bidirectional and unidirectional modes of operation. This chapter describes the use of DV- units in typical bidirectional and unidirectional applications and five specific applications: bidirectional applications unidirectional applications single DS3 feed application multiple DS3 feed application data interface application hubbing to an OC12 application hubbing from a DVN application Bidirectional applications Typical bidirectional applications include: point-to-point between DV- units (see Figure 4-1) point-to-point between a DV- unit and a SONET TBM shelf (see Figure 4-2) DV- unit interfacing as a tributary to a SONET OC12 TBM transport shelf (see Figure 4-3). In each application, the default DV- unit switch 1 and switch 2 options (all set to 1) would be used.

In the first form, only DS3 signals are transmitted from a site (see site A in Figure 4-4). In the second form, DS3 signals are received and then the same or a different DS3 signal is reinserted (see site B in Figure 4-4) for transmission to the next site (see site C in Figure 4-4). In the second form, the DV- unit acts as an Add/Drop multiplexer. Figure 4-4 Unidirectional applications DS3 site A site B site C DV- o DV- o, OC12, or DV- DS3 Digital Video Codec DV FWP Standard

If a DV- unit is NOT being used, the Line FERF alarm must be turned OFF on the or OC12 product. Note 2: DV- units do not support SONET DCC; therefore, the SONET DCC link fail alarm will always be ON. The alarm must be turned OFF on the and OC12 product. Note 3: When a DV- unit STS channels are set as Unequipped, a STS Rx Unequipped alarm will be generated. The alarm must be turned OFF on the and OC12 product. Note 4: See Provisioning and Operations Procedures, , for alarm provisioning on Nortel and OC12 TBM shelf products.
