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 y ou by y our Ser vice Provider . If you are using two Model 2715s together as short range modems, set both units to HDB3. SW4 Line F r aming & Coding Off HDB3 On AMI Line Coding Options: High Density B[...]

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 f our bit[...]

NO TE: When the data rate is set to 2.048Mb/s, then the unit is f orced into G.703 mode, and it transmits user data on all 32 times- lots. There is no framing inf or mation; theref ore, the CAS MF (SW2)and CRC-4 (SW3) s witches are ignored. In all other rate settings, the unit emplo ys G.704 framing; TS0 is reser ved f or sig- naling. 3.2 SOFTW ARE[...]

3.2.1 Introduction to Main Men u After entering the password, y ou may access all of the system’ s functions and parameters. The Main Menu looks lik e this: HELPFUL HINTS 1. T o mak e a selection, key the highlighted letter that corre- sponds to a menu selection. 2. T o e xecute the selection, type [Enter/CR]. 3. T o toggle between options on a h[...]

3.2.2 System Configuration The System Configuration menu looks lik e this: The System Configuration options are described below: Line Format: G.703 (def ault) 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 interf ace (NI). CAS MF and CRC-4 are disabled. G.704: G.704 res[...]

Clocking : Network (def ault) 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 recov ers the clock from the receiv ed signal and uses it to transmit data. In this wa y the unit remains synchronized to a master clock. In campus applications, one o[...]

3.2.3 System Diagnostics The System Diagnostics/Statistics screen looks like this: NO TE: This screen is updated once per second. The System Diagnostics/Statistics options and functions are described below . Local Loop Idle (def ault) The Local Loop is a bi-lateral loopbac k in which the data from the local DTE and the data from the remote unit are[...]

22 21 Remote Loop Idle (def ault) The Remote Digital Loopback (RDL) test chec ks the performance of both the local and remote Model 2715s, as well as the comm unica- tion link between them. Data from the local DTE is sent across the entire communication circuit and looped bac k to the local DTE. The Model 2715 Initiating a RL can be in one of the f[...]

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 sho wn 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 consecutiv e zeros hav e been [...]

25 26 Loop Timeout The Loop Timeout setting can be set to one of the follo wing: 00:05 = five min utes 00:10 = ten minutes 00:15 = fifteen minutes 00:30 = thir ty minutes (def ault setting) 00:45 = f or ty-five minutes 01:00 = one hour 01:30 = 90 minutes 02:00 = two hours 03:00 = three hours NEVER = f orev er—the unit will remain in loopback with[...]

27 28 4.3 PO WER CONNECTION The Model 2715 off ers three ways to supply e xter nal power: A C power , DC po wer and interface po wer . 4.3.1 Using the A C Po wer 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 po wer supply is equipped with a male IEC-320 power[...]

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 cloc k. ALM The alarm LED indicates the presence of a AIS or RAI, or Out of F rame condition. The ALM LED will[...]

31 32 T o perf or m an RDL test, follo w these steps: 1. Activate RDL. This ma y be done in two wa ys: 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 ” [...]
