Port Config (Port Configuration)
The menu item
PORT
is used to select and then to configure
the parameters associated with the high-speed serial
interface.
INTERFACE
This option sets the electrical interface for the Nx56/64 port.
TS0 RATE
This sets the base rate of the interface. The actual data rate
depends on the number of time slots that are used.
Choices: 56K; 64K
MAPPING
This sets the unit to use alternate or contiguous channels in
the E1 data stream. If more than 16 channels are used in CCS
mode, contiguous must be used. If more than 15 channels are
used in CAS mode, contiguous must be used. If other than a
private network is used, the carrier must be notified of this
choice.
Choices: ALT (alternate); CONT (contiguous)
DTE TX CLOCK
Controls the clock used by the ESU L to accept the transmit
(TX) data from the DTE. Most applications will allow for this
to be set to
INTERNAL
. If the interface cable is long (causing a
phase shift in the data) the clock can be selected as
INT/INV
(Internal/Inverted). This switches the phase of the clock
which should compensate for a long cable.
The factory default setting for this option is
AUTO
. The
AUTO
DTE TX CLK
setting will allow the ESU LT to automatically
detect the delay from the DTE device to the ESU LT and set
the proper phase of the clock.
AUTO DTE TX CLK
is not
available in unframed mode.
This feature will automatically select between the
INTERNAL
and
INT-INV
settings. If the DTE provides a clock with TX
data, the clock selection is set to
EXTERNAL
. The ESU LT will
depend on an externally supplied clock to accept the TX data.
Choices: INTERNAL; INT-INV; EXTERNAL; AUTO
