700-701-100-02 Functional Description FUNCTIONAL DESCRIPTION This section provides a functional description of the line and desktop units, including major components, single-pair application mode, alarms, and testing (including monitoring and loopbacks). MAJOR COMPONENTS The major components of the line and desktop units include: • G.
Functional Description 700-701-100-02 G.703 Interface The G.703 interface performs the following functions: • provides a jumper-selectable 75 or 120 Ω DTE interface (see “Installation and Startup” on page 23 for jumper locations) • allocates full or fractional portion of the total 2048 kbps bandwidth to and from the G.703 interface • frames data according to G.704 • inserts an idle code into unused time slots at the G.703 output • recovers timing from the received G.
700-701-100-02 Functional Description Power Sources The line and desktop units receive power from the following sources: • A shelf-mounted UTU-701C receives power from a local source of -36 Vdc to -72 Vdc. • An enclosure mounted UTU-701C receives power from a local source of -36 Vdc to -72 Vdc or from the enclosure’s built-in AC-to-DC power supply (when provided). • The ETU-751C desktop unit receives power from a source of 100 to 240 volt, 50 or 60 Hz, AC power.
Functional Description 700-701-100-02 RATE SELECTABLE APPLICATION MODES AND OPTIONS Applications for single-pair rate-selectable HDSL are those that require transport of voice and data at various rates over various distances on a single pair of wires. Depending on line noise and the HDSL rate selected, spans of up to 7.1 km (4.4 miles) can be deployed without the use of doublers. The HDSL line rate depends on the number of time slots selected.
700-701-100-02 Functional Description Table 7. Typical Structured Mode System Settings Options Setting Application Mode <32 TS (Structured) LTU Interface Primary Timing Source G.703 G.703 Port CRC-4 Mode Enabled Idle Code FF Data Rate / # of TSs 1536 kbps / 24 Beginning TS 1 NTU Interface Primary Timing Source G.703 G.703 Port CRC-4 Mode Enabled Idle Code FF Data Rate / # of TSs 1536 kbps / 24 Beginning TS 1 For applications requiring fractional use of the G.
Functional Description 700-701-100-02 Unstructured Mode When 32 time slots are selected, the line and desktop units automatically operate in the unstructured mode (see “G.704 Framing and Rate Selectable HDSL” on page 17). There is no unstructured menu selection. In the unstructured mode: • There is no G.704 framing. • Time slot 0 is the beginning time slot, and the data rate is fixed at 2048 kbps. • A transparent transmission channel is provided between the local and remote units.
700-701-100-02 Functional Description G.704 Framing and Rate Selectable HDSL Time slots 0 and 16 are always transported in accordance with the G.704 framing standard. Although not used by G.703 to transport data, the rate-selectable HDSL interface treats time slots 0 and 16 as a 128 kbps increase in the HDSL payload rate. For example, when 4 time slots are selected (256 kbps), time slots 0 and 16 are transported along with the selected time slots, 1 though 4.
Functional Description 700-701-100-02 PERFORMANCE MONITORING AND HISTORY The UTU and ETU units provide extensive real time, non-disruptive monitoring of HDSL transmission performance parameters for all units in a circuit. Performance of the user interface ports is also monitored.
700-701-100-02 Functional Description Table 11. HDSL Transmission and Application Interface Alarms Alarm Description HDSL Alarms HDSL alarms include: Margin (MAR) Margin has fallen below threshold set for the HDSL interface. Errored Seconds (ES) Errored seconds count has exceeded threshold set for the HDSL interface. Loss of Sync Word (LOSW) G.703 Alarms Loss of sync word at the HDSL interface. Remains active during restart, but not a cold start. G.

Inspection, Safety, and Equipment Repair 700-701-100-02 INSPECTION, SAFETY, AND EQUIPMENT REPAIR This section describes the procedures to be followed regarding product inspection, safety, and repair. INSPECTION Open the line or desktop unit shipping carton and inspect the contents for signs of damage. If the equipment was damaged in transit, immediately report the extent of the damage to the transportation company and to ADC (see “Product Support” on page 69).
700-701-100-02 Installation and Startup INSTALLATION AND STARTUP This section describes the installation and startup procedures for the line and desktop units. UTU-701C LINE UNIT INSTALLATION Perform the following steps to install the UTU-701C line unit. The chassis ground of the shelf or remote enclosure receiving these units must be connected to earth ground for protection of the equipment and for safety of personnel. Primary protection for the HDSL line must be provided by the user.
Installation and Startup 700-701-100-02 The line and desktop units will reset and their LEDs will sequence through the startup cycle following any change to the Local Unit Role option. If necessary, log on again by pressing the SPACEBAR several times. ETU-751C DESKTOP UNIT INSTALLATION Perform the following steps to install an ETU-751C desktop unit. 1 Insert the AC power cord into the power cord receptacle on the ETU rear panel.
700-701-100-02 System Configuration SYSTEM CONFIGURATION Each line unit provides a system-wide view of the entire HDSL circuit, including the remote unit. After establishing communication with the remote line card, provisioning information can be set and performance can be monitored from the local unit. If the HDSL link is down, the only parameters that can be changed are those on the local line unit. The LTU overwrites any NTU settings when the link is re-established.
System Configuration 700-701-100-02 To connect and configure a maintenance terminal: 1 Connect a serial cable from the maintenance terminal 9-pin COM port to the line or desktop unit console port connector (Figure 11). Ensure the Data Terminal Ready (DTR) signal from the terminal is connected as the HDSL card will not communicate without it. Data Terminal Ready (DTR) may also be asserted by connecting the DSR output signal (pin 6) to the DTR input (pin 4).
700-701-100-02 System Configuration LOGGING ON To log on to the maintenance terminal console screen: 1 Press the SPACEBAR several times to display the Logon Password screen (Figure 12). Figure 12. Logon Password Screen The ENTER key is the factory default password. If you establish a different password, you must type the new password (single word, no spaces, up to eight characters) on a subsequent log on.
