4. Forcing the ST to acquire a link
1. The ‘LK’ command forces the ST to acquire a link as follows:
RW
Code
PN
Code
Up Link
Rate *
Down Link
Rate*
Overlay
code
Frequency channel number
within channel plan
LK 8 1 4 4 0 9
* The rate at which the link will acquire is defined as follows:
1: 10kbit/s
2 40kbit/s
3 80kbit/s
4: 160kbit/s
2. With the LAT connected to the ST, ensure that the ST has booted-up, type:
TE 0 Puts ST into test mode
W 426 Watch the link state
LK 7 1 1 0 0 9 Acquire a downlink on TLAC (in this example RW 7, at
10kbit/s channel 9)
LK 8 1 4 4 0 9 Acquire a downlink and uplink on TTC (in this example RW 8
at 160kbit/s channel 9
3. During these commands, the link status ‘watch’ should return the states as
described in paragraph 2. The final state should be ‘0B0B’
4. The ST now acquires, if the ST fails to acquire the ST is faulty.
5. To take the ST out of test mode, type: TE 1.
5. Returning RW codes to system use:
At the Central Terminal With LAT connected to DTU card, type:
EA 39:0/3A:03B:7
To return RW code 7 to system use
ES 0
To return RW code 8 to system use
EA 39:0/3A:0/3B:8
ES 0
