Chapter 1 Introduction PASSTHRU OVER VIEW The DSX-1 Passthru is one of the secondary interface option modules available for use with the ADTRAN TSU 100/600. The Passthru option card should be selected to provide DSX-1 access for PBXs, or other equipment, that use a DSX-1 interface.
• Provides timing for the TSU 100/600 as an option • Displays menu options for easy configuration • Executes an extensive self test Inter f aces The DSX-1 Passthru Option Module has the following interfaces: • DSX-1 per ANSI T1.102 • Interface connectors RJ48C and DB15 •...
The Passthru is an option module which plugs into the option slot in the rear of the TSU 100/600. See Figure 1-1. Figure 1-1 DSX-1 Passthru Option Module The Passthru rear panel includes a plastic plug over a cutout for a V.35 connector. This allows a V.35 Nx56/64 interface plug-on card to be added to the Passthru card, part number 1200053L1.

For the TSU 100/600 application, there is only one option slot. Therefore the port designation for the Passthru port is 1.1. If added, the Nx56/64 port designation would be 1.2. These port numbers appear in the front panel LCD menu displays. DSX-1 Passthru Option Module 61200.055L1-1C...

Figure 3-2 Port Status Display An asterisk is displayed under the CRC if there are CRC errors in extended superframe format (ESF) mode. If the DSX-1 is configured for D4 Frame format, the LCD displays n/a. 61200.055L1-1C DSX-1 Passthru Option Module...
Chapter 3. Operation An asterisk is displayed under the BPV if the DSX-1 is detecting bipolar violations. An asterisk is displayed under the XS0 if the DSX-1 is detecting excessive zeroes. (Eight consecutive zeroes in B8ZS or 16 consecutive zeroes in AMI.) An asterisk is displayed under the FER if the DSX-1 is detecting frame bit synchronization errors.
In-band Loopback sets the Passthru to accept or reject in-band loopup and loopdown codes (per ANSI T1.403 specification) which may be sent to the card over the DSX-1 interface. This loopback is a line loopback. Clock Sour ce Clock Source selects the clock source for transmission toward the PBX or device connected to the Passthru.
TSU 100/600 User Manual. Line Loopback On the Passthru card, the line loopback causes data received at the DSX-1 interface to be looped back toward the DTE (PBX) achieving a local loopback. Port Loopback The port loopback is internal and loops all data mapped to the Passthru back toward the network interface on the controller.
