7-10 E&M Ports
Model No.
Running Head
PATTRN
The Pattern is the outgoing test pattern to be sent to the selected port by the system. You can
send a different pattern to each port. The none setting disables the test pattern. The D-mW
(Digital milliwatt) option sends a 1 kHz tone at 0.0 dBm. The setting of the Rx TLP field
adjusts the D-mW signal level before sending the signal to the CPE.
SIG CONV
The Signaling Conversion parameter allows you to change the transmit ABCD signaling bits
from CCITT (E1) to ANSI (T1) standards, and is accessd by selecting B from the taBs option
at the bottom of the window.
The options are off if ANSI signaling is used and on to convert transmit signaling from ANSI
to CCITT format according to the Interface Card Conversion Table for E&M signaling. This
setting also converts receive signaling from CCITT to ANSI. To see the options currently
deployed on a port, Figure 7-7 shows the default settings for the conversion table. This table
will be commonly used by all ports to which the this option is set to on.
The C->A column describes conversion done in the downstream direction towards the
subscriber loop, while the A->C column describes the conversion done in the upstream
direction, normally towards the T1 interface.
