Paradyne 3616, 3615 manual Connecting the DSU to a Router, Connecting to DDS or Lads Network

Installing the Model 3616 DualFlow DSU

Connecting to the

DDS (or LADS) Network

NOTE

Before connecting the DSU to the DDS network, ensure that approved primary protectors have been installed on the circuit in accordance with Article 800 of the National Electric Code, NFPA 70, in the United States and Section 60 of the Canadian Electric Code, Part 1, in Canada.

If connecting the DSU to a LADS network there are distance limitations that govern the use of DSUs on the network. Table 2-2 in Chapter 2 summarizes these limitations.

The DDS network interface is provided by two RJ48T

50-pin connectors on the back of the carrier (refer back to Figure 3-2, DDS Interface). Each connector serves eight contiguous slots in the carrier: one for Slots 1 through 8 and one for Slots 9 through 16.

Appendix E provides connectivity diagrams should you need further assistance in connecting the DSU to the network.

Connecting the DSU to a Router

The rear connector plate provides the router interface for the Model 3616 DSU. Each rear connector plate contains two DB25 (or 25-pin D-type) connectors. The top connector is an EIA-232-D/V.24 (ISO 2110) connector. The bottom connector is a CCITT V.35 (ISO 2593) connector.

For the 25-pin V.35 connector, use a V.35 Interconnect Cable (feature number 3000-F1-510). This cable provides the interface between the 25-pin V.35 D-type connector and a V.35 router cable.

Appendix E provides connectivity diagrams should you need further assistance.

The DualFlow DSU transmits user data through its V.35 interface, and diagnostic or user data through its EIA-232-D/V.24 interface. Cabling is based upon the preset configuration (SyBC, SyBT, or DiDg) selected in the Opts subbranch (Config branch).

.Procedure

1.Install the V.35 Interconnect Cable as described in Step 8 of the Installing the DSU section of this chapter.

2.Connect the plug end of the router's V.35 cable to the DSU's V.35 connector.

Tighten the two holding screws.

3.Connect the other end of the router's V.35 cable to the router's primary serial port.

Tighten any holding screws.

4.Connect the plug end of the router's EIA-232 cable to the DSU's EIA-232-D/V.24 connector.

Tighten any holding screws.

5.Connect the other end of the router's EIA-232 cable to the router:

•If the DSU is to be configured using the SyBC or SyBT configuration, connect to the router's secondary serial port.

•If the DSU is to be configured using the DiDg configuration, connect to the router's console port.

Tighten any holding screws.
