Zhone Technologies IMACS-200 manual Tabs Signal Conversion Change Mode

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 7-7shows 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.
