Description

CRC

n1 n2

Cyclic redundancy check error count. Range is 1-(201)-255 for
n1, 1-(97)-255 for n2.

where

n1

is multiplied by 4 to obtain the actual count, giving an

actual count range of 4-1020.

FAP

n1 n2

Frame alignment problem error count. Range is 1-(28)-255 for
n1, (1)-255 for n2.

RATS

1-(10)-15

Number of seconds firmware has to check BPV/CRC/FAP for
excessive error rate.

GP2

T2 mt dt ct ot

Group 2 error thresholds.
This is the maximum amount of time that can elapse before
software checks the associated thresholds of 120 to 32,640
msec and rounds it to the closest multiple of 128 msec.

where

T2

= Error count values are in the range 1-(20)-255.

mt

= Maintenance threshold time (MNT)(default =100S).

dt

= No new data calls threshold time (NNDC)(default =12S).

ct

= No new calls threshold time (NNC)(default =12S).

ot

= Out of service threshold time (OOS)(default =4S).

Note 1: The following requirements must be met for input mt
= >dt = >ct = >ot.

Note 2: Threshold times are one of the following: nnnnT, nnnS,
nnnM, or nnH, where nnnn is and integer and T,S,M, or H show
the increments of use. The values are as follows:
-nnnnT is the time in 20 millisecond increments (nnnn = 20-5000)
- nnnS is the time in 1 second increments (nnn= 1-240)
- nnnM is the time in 1 minute increments (nnn= 1-240)
-nnH is the time in 1 hour increments (nn= 1-24)

MNG1

nnnM

Maintenance Guard time Group 1, default = 15M.

NCG1

nnnM

No New Calls Guard time Group 1, default = 15M.

OSG1

nnnM

Out Of Service Guard time Group 1, default = 15M.

MNG2

nnnS

Maintenance Guard time Group 2, default = 15S.

NCG2

nnnS

No New Calls Guard time Group 2, default = 15S.

OSG2

nnnS

Out Of Service Guard time Group 2, default = 15S.
