17 Note If the 2073RC is being used for priv ate shor t-range modem applications, the twisted-pair cab le connected to its por t will need to be a cross-ov er cable.
18 4.0 INSTALLATION This section describes the functions of the Model 1001R14 rack chassis , tells how to install front and rear Model 2073RC Series cards into the chassis, and ho w to connect to the twisted pair interface and the serial interf ace. 4.
19 P owering up your 1001R14 rac k The power supplies that come with y our 1001R14 rack system are equipped with a power entry connector on the rear power supply card. The power supplies are hot-s wappab le, so you are not required to remov e the cards from the rack while applying po wer to the system.
20 Note Pin-out requirements for tail circuit applications v ar y between equipment manuf acturers. If you hav e any questions about a specific installation, please contact P atton Electronics T echnical Suppor t.
21 5.0 OPERATION Once the 2073RC is installed and configured properly it is ready to place into operation.This section describes the function of the LED indicators, and the use of the loopback and pattern test modes. 5.1 LED DESCRIPTIONS The 2073RC is equipped with 12 LED indicators that monitor the status of communication.
22 Loop (V .54 & T elco) Diagnostics The 2073RC off ers tw o loop diagnostics for diagnosing the 2073RC and any communication links . These tests can be activ ated via signals on the serial por t interface or the front panel s witch.
23 Operating Remote Digital Loopback (RDL) The Remote Digital Loopback (RDL) test chec ks the performance of both the local and remote 2073RC as well as a point-to-pointcommunication link between them. Any characters sent to the remote 2073RC in this test mode will be returned back to the originating device (i.
