Remote Taking too long to acquire into the network

Hello Team,

We have below network config:

Outbound:
Modulation: ACM
Error Correction: LDPC BCH
Symbol Rate: 144400 Ksym
FEC Blocks per Frame: 1800
Frame Lenght: 125 ms

Inbound:
Modulation: QPSK
Error Correction: 2D 16s-170bytes (3/4)
Symbol Rate: 450 ksym
Acquisition Aperture: 773 sym
Traffic Slot: 57

On outbound, provider has given only 1024 Kbps.

We have approx 73 remotes in the network but all remains down except 3 sites are up. Problem is that remote takes 8 to 10 minutes to acquire into the network.

I would like to know how long remotes should take to acquire and how can i calculate?

Thanks & Regard,

Dhrisht

After the modem is fully booted up, you should see your modem begin aquisition after just a few sweeps, You will see a remote_hello cmd followed by power adjustments coming in from the Hub. Never actually timed it but it should be way less than 8 minutes (more like 2-3 minutes total - including boot process)
What model/type LNB's are you running? And are you sure the Geo's are good on the remotes that are not bursting into the net?

what about initial and maximum power settings? may be it is causing the delay.

Hello,
Check also the GPS Position accuracy for the remote not acquiring quickly ...
