7. HDSL4 DEPLOYMENT GUIDELINES

The different segments of an HDSL4 circuit are defined in Figure 26.

Figure 26. HDSL4 Circuit Segments

The ADTRAN HDSL4 system provides DS1-based services over loops designed to comply with the guide- lines given below. These guidelines apply to the following circuit configurations:

•a single segment or an HDSL4 circuit with no H4Rs,

•a circuit having two segments (with one H4R), or

•a circuit having three segments (with two H4Rs).

The guidelines reflected herein are for worst-case scenarios, that is, for loops that contain a maximum amount of disturbers, noise, etc. Actual deployment guidelines may vary based on local policy. Please refer to those guidelines on an as-necessary basis to ensure optimum performance.

Designing a circuit with loop attenuation greater than the recommended maximum loss may result in compro- mised reliability of that loop. Follow the guidelines in in this section to ensure that the circuit meets basic requirements:

1.All loops are nonloaded only.

2.Any single bridged tap is limited to 2 kft.

3.Total bridged tap length is limited to 2.5 kft.

4.Bridge tap within 1000 feet of units may affect performance of the circuit.

5.Loop Attenuation Limits. See Table 6.

6.DSL-Recommended Range Limits. See Table 7 and Table 8.
