1.2 RADIO AND TV INTERFERENCE The Model 2715 generates and uses radio frequency energy, and if not installed and used properly—that is, in strict accordance with the manufacturer's instructions—may cause interference to radio and tele- vision reception. The Model 2715 has been tested and found to com- ply with the limits for a Class A computing device in accordance with the specifications in Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection from such interference in a...
Thank you for your purchase of this Patton Electronics product. This product has been thoroughly inspected and tested and is warrant- ed for One Year parts and labor. If any questions arise during installa- tion or use of the unit, contact Patton Electronics Technical Services at (301) 975-1007.
The Model 2715 features configuration capability via hardware switches or a software control port. This section describes all possible hardware and software switch configurations of the Model 2715. 3.1 DIP SWITCH CONFIGURATION The Model 2715 has eight internal DIP switches that allow configu- ration for a wide range of applications.
Switch SW2: CAS Multiframe The Channel Associated Signaling (CAS) multiframe uses Timeslot 16 (TS16) to send multiframe (MF) alignment data. In CAS MF, a multi- frame is defined as 16 frames, where a frame consists of 32 64kb/s timeslots, numbered 0 to 31. TS16 of the first frame in the MF contains the CAS MF alignment word in the upper four bits.
NOTE: When the data rate is set to 2.048Mb/s, then the unit is forced into G.703 mode, and it transmits user data on all 32 times- lots. There is no framing information; therefore, the CAS MF (SW2)and CRC-4 (SW3) switches are ignored. In all other rate settings, the unit employs G.704 framing;...
3.2.1 Introduction to Main Menu After entering the password, you may access all of the system’s functions and parameters. The Main Menu looks like this: HELPFUL HINTS To make a selection, key the highlighted letter that corre- sponds to a menu selection. To execute the selection, type [Enter/CR].

3.2.2 System Configuration The System Configuration menu looks like this: The System Configuration options are described below: Line Format: G.703 (default) Options: G.703, G.704 G.703: G.703 is unframed, 2.048Mb/s. In this case, the DTE rate is equal to the line rate at the network interface (NI). CAS MF and CRC-4 are disabled.

Clocking: Network (default) Options: Network, Internal, External Network: This is the most commonly used setting when connect- ing to a carrier’s network. In this mode, the unit recovers the clock from the received signal and uses it to transmit data. In this way the unit remains synchronized to a master clock.

If you do not have a terminal, you may force the unit to use the DIP switches as the default configuration source by turning off the unit, set- ting all the DIP switches to the ON position, then powering on the unit. This will cause the unit to enter a special mode.

Remote Loop Idle (default) The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 2715s, as well as the communica- tion link between them. Data from the local DTE is sent across the entire communication circuit and looped back to the local DTE. The Model 2715 Initiating a RL can be in one of the following states: Idle...

Use this option to select the test pattern used to test the link. NI STATUS The Network interface (NI) status is shown in the middle of the Diagnostics/Statistics screen. The brackets are empty when the link is operating normally. Only one error message is provided Receiver Carrier Loss [RCL] occurs when 255 consecutive zeros have been detected at the network interface.
Loop Timeout The Loop Timeout setting can be set to one of the following: 00:05 = five minutes 00:10 = ten minutes 00:15 = fifteen minutes 00:30 = thirty minutes (default setting) 00:45 = forty-five minutes 01:00 = one hour 01:30 = 90 minutes 02:00 =...
4.3 POWER CONNECTION The Model 2715 offers three ways to supply external power: AC power, DC power and interface power. 4.3.1 Using the AC Power Supply (100-240VAC) The Model 2715 uses a 5VDC, 2A universal input 100-240VAC, power supply (center pin is +5V). The universal input power supply is equipped with a male IEC-320 power entry connector.

The Loss of Sync LED lights when the unit loses synchronization with the incoming sig- nal. This may happen when there is a fram- ing mismatch or a loss of signal. In unframed mode, the LOS LED monitors the status of the transmit clock. The alarm LED indicates the presence of a AIS or RAI, or Out of Frame condition.

To perform an RDL test, follow these steps: Activate RDL. This may be done in two ways: Enter Remote Loop from the System Diagnostics/Statistics menu and toggle the <Spacebar> until “TM” appears next to the Remote Loop option.; Activate the “RL” signal on the DTE. If you are not sure which lead is the “RL”...
