Switch S1-1: RDL Type

Switch S1-1 selects the type of Remote Digital Loopback that the 2720 will initiate when the RDL is initiated from this unit. The 2720 will respond to both the V54 and the CSU loopback regardless of the set- ting of S1-1

S1-1

RDL Type

On

Initiate a V.54 RDL loop when selected

Off

Initiate a CSU loopback when selected

Switch S1-2: Reserved

Switch S1-3:Tx Clock Invert

Switch S1-3 allows the user to invert the transmit clock originating in the 2720. When S1-2 is set for transmit clock, it may be necessary to invert the transmit clock to allow for delays due to long cables.

S1-3

Tx Clock Invert

On

Transmit clock is inverted

Off

Transmit clock is normal

Switches S1-4 and S1-5: Line Build Out

Use Switches S1-4 and S1-5 to set the Line Build Out (LBO). The Line Build Out varies the pulse shape and attenuation of the signal sent to the network. The amount of Line Build Out depends on NetLinkª T1Õs distance to the last repeater. The telephone company providing the service will advise on the amount of LBO necessary. In most cases the default setting will suffice.
