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 2094s together as short range modems, set both units to HDB3.
CLOCK MODES Network Clock T ransmitter timing is derived from the received line signal. Internal Clock T ransmitter clock is derived from an internal clock source. External Clock T ransmitter timing is derived from the local DTE device. V alid only in unframed mode.
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) switch is ignored. SW3 is defaulted to clock mode. In all other rate settings, the unit employs G.
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.
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).
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.
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 .
22 21 Remote Loop Idle (default) The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 2094s, 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.
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.
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.
27 28 4.3 POWER CONNECTION The Model 2094 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 2094 uses a 5VDC, 2A universal input 100-240V AC, power supply (center pin is +5V).
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.
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.
