Switch SW1: Line Coding Use Switch SW1 to control the Network Line Coding options. Set these options to be the same as the Line Coding given to you by your Service Provider . If you are using two Model 2715s together as short range modems, set both units to HDB3. SW4 Line Framing & Coding Off HDB3 On AMI Line Coding Options: High Density Bipola[...]

Switch SW2: CAS Multiframe The Channel Associated Signaling (CAS) multiframe uses T imeslot 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 timeslots. 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; TS0 is reserved for signaling. 3.2 SOFTW ARE CONFIGURA TI[...]

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 1. T o make a selection, key the highlighted letter that corre- sponds to a menu selection. 2. T o execute the selection, type [Enter/CR]. 3. T o toggle between options on a highlig[...]

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. G.704: G.704 reserv[...]

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. In campus applications, one of th[...]

3.2.3 System Diagnostics The System Diagnostics/Statistics screen looks like this: NOTE: This screen is updated once per second. The System Diagnostics/Statistics options and functions are described below . Local Loop Idle (default) The Local Loop is a bi-lateral loopback in which the data from the local DTE and the data from the remote unit are lo[...]

22 21 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 follo[...]

23 24 Use this option to select the test pattern used to test the link. NI ST A TUS 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 det[...]

25 26 Loop Timeout The Loop T imeout 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 = two hours 03:00 = three hours NEVER = forever—the unit will remain in loopback without use[...]

27 28 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 (100-240V AC) The Model 2715 uses a 5VDC, 2A universal input 100-240V AC, power supply (center pin is +5V). The universal input power supply is equipped with a male IEC-320 power entry conne[...]

29 30 LOS 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. ALM The alarm LED indicates the presence of a AIS or RAI, or Out of Frame condition. The ALM LED will b[...]

31 32 T o perform an RDL test, follow these steps: 1. Activate RDL. This may be done in two ways: a. Enter Remote Loop from the System Diagnostics/Statistics menu and toggle the <Spacebar> until “TM” appears next to the Remote Loop option.; b. Activate the “RL” signal on the DTE. If you are not sure which lead is the “RL” signal, [...]
