Parameter Description
Setting
modes are available:
Preferred clock
: The TE80
uses its internal clock and
provides the clock to the
endpoint connected to its 4E1
port. To place a point-to-point
call, set
Clock mode
for either
endpoint to
Preferred clock

Alternate clock 4
: The TE80
obtains a clock from any of
these lines.
master clock and the TE80 clock
as the slave clock.
If the TE80 is connected to another
endpoint, set one endpoint's clock
as the master clock and the other's
to slave clock.
Signaling
mode
Specifies the transmission mode
for 4E1 signaling.
The Cyclic Redundancy Check
(CRC) is used to test the network
quality, and CRC results indicate
frame error rates. When you select
an option that contains
CRC4
, the
TE80 tests the network for bit
errors.
To use channel associated
signaling, select
CAS
.
To use common channel signaling,
select
CCS
.
Sensitivity
Specifies the sensitivity of the
receive equalizer.
Set this parameter based on the
length of the 4E1 line used
between the TE80 and the nearest
network node such as a switch.
If the length of the 4E1 line used
between the TE80 and the nearest
network node exceeds 100 meters,
select
Long line
.
If the length of the 4E1 line used
between the TE80 and the nearest
network node is less than 100
meters, you can select
Long line
or
Short line
.
Long line
is
recommended because it provides
a higher sensitivity.
