The display shows the status of the following:
• 9.6 - indicates the DAP's operating speed (9.6 Kbps). Possible displays
range from 2.4 to 64 Kbps. Actual speeds displayed are dependent on the
service used. An OOS is displayed when an Out of Service code is being
received from the network. Loop is displayed when a network service
loop command is being received. In DDS-SC mode, an ASC is displayed
when an Abnormal Station code is being received.
• TL - shows the DAP's transmit level in dBm. The transmit level is fixed
for units equipped with the 15P09AA or Model D Aggregate card.
• RL - shows the DAP's approximate receive level insertion loss range in -dB
for units equipped with the 15P09AA or Model D Aggregate card. For
example, -11 dB indicates the received signal is less than 11 dB. Table 6-1
lists the receive level insertion loss ranges for each line rate. For units
equipped with the Model A or C Aggregate card, RL shows the DAP's
receive level in -dB.
• Q - shows the quality of the signal received from the telephone line.
Receiving any network control code (except Control Mode Idle), a loss of
multiport frame, and unknown control codes will cause the signal quality
to degrade. Possible displays are Best, Good, Fair, Poor, and Off.
• Dial - indicates whether the DAP is in dial backup operation. If the unit
is not equipped with the Analog, Switched 56, or ISDN IDBU option, Svc
is displayed in place of Dial. Svc - shows the digital data service,
LADC, or LDM line used. Possible displays are DDS, DDSNI, DDSSC,
LADC, LDM, CC64, and C64NI.
• Tst - indicates whether a test is in progress.
