Specifications

214 IBM Voice Over Frame Relay Perform Guide
BERT Format:dsbechdp
Controls the DS0 channel (ch) on which the bit
errror rate test (BERT) will be transmitted, the
transmission direction (d), and test pattern (p).
Direction: s (subscriber) or n (network). Test
Pattern: 5 (511) or q (QRSS). DSUB must be offline.
BERT Inject
Error
Format:dsbei
Configures DSUB bit error rate test to inject a
single-bit error into the BERT bit pattern.
BIT Format:dsbi
Initiates the same built-in test (BIT) that is executed
during unit reset, and when the IBM 9783 unit is
initially turned on. DSUB must be offline.
CAS Format:dscam
Controls the DSUB Channel Associated Signalling
(CAS). Set mode (m) to e (enable) or d (disable).
Disable CAS when Common Channel Signalling
(CCS) is used. Command is valid only for T-1 DSUB.
Note: Making any change to CAS setting initiates
the DSUB switch command.
Clear_stat Format:dscl
Clears alarm statistics for the DSUB port.
Distance Format:dsdil
Configures the DSUB T-1 port pulse shaping
function based on the length (l) of the loop in feet.
Length: 0 (0 to 133), 1 (133 to 266), 2 (266 to 399),
3 (399 to 533) or 5 (533 to 655). Command is valid
only for T-1 short-haul DSUB.
DMW Disable Format:dsdmd
Disables the digital milliwatt test.
DMW Format:dsdmchd
Applies a digital milliwatt (DMW) 1000 Hz 0 dBm0
test signal to the selected DS0 channel (ch) in the
specified direction (d). Direction: s (subscriber) or n
(network). DSUB must be offline. Channel ch must
be mapped.
Framing E-1 Format:dsffrm
Sets framing format (frm) for an E-1 DSUB
subscriber port. E-1 Framing format: c(CRC_MF) or
t (TS16_MF). Mode: e (enable) or d (disable). DSUB
must be offline.
