Time Slot
Configuration
To set the T1 Time Slot configuration:
1. Set the two-position DIP Switch - 1 = OFF, 2 = ON.
2. Set the 12-position DIP Switch to select the configuration.
3. Depress the NVM RESET / CONFIG push button for at least one second to enter
the parameters in the unit’s NVM.
The meaning of the 12-position DIP Switch settings are shown in Figure 4-3 and de-
scribed as follows:
Switch positions 1 - 5 represent (in binary format) the number of time slots used in the
T1. FT1 service ranges from 1 to 23 time slots. A value of 0 or any value 24 or above
indicates service is full T1.
Switch positions 6 - 10 represent (in binary format) the starting DS0 (1 - 24).
Switch position 11 selects contiguous or alternating DS0s from the starting DS0.
Switch position 12 selects the DS0’s data rate, 56 or 64 Kbps.

WAN DLCI
Address
To use the in-band WAN Frame Relay Management Channel, the WAN Management
DLCI (Frame Relay Management Channel’s PVC Address) must be set.
The DIP switch settings are read and stored in the unit’s NVM when the recessed push
button labeled “NVM RESET / CONFIG” on the unit’s rear panel is pressed (unit must
have completed its power-on self-test).
The WAN DLCI is stored by entering two settings of the DIP switches as follows:
1. Set the two-position DIP Switch - 1 = OFF, 2 = OFF
2. Set 12-position DIP Switches to either:
a) All switches OFF to select Dedicated WAN management PVC.
b) All switches ON to select Tunneled WAN management PVC.
3. Press the NVM RESET / CONFIG push button and hold for at least one second.
4. Set the 12-position DIP Switch to desired DLCI value (see Example Figure 4-4.)
5. Press the NVM RESET / CONFIG push button and hold for at least one second.
NOTE: An invalid DLCI value will be ignored (valid values are: 16-991.)
