Configuration Window 4-5
Loopback State (Default - Disable); options: Disable, Remote, Internal
Setting this parameter to Remote will cause a loopback of the incoming
data and clock to the transmit data and clock (this option is not supported
with E1). Internal Loopback will cause a loopback of the transmitted data to
the receive port.
SONET/SDH Frame
Type (Default - STM-1); options: STS-3c, STM-1
This parameter is only used in 155 Mbps cards. It defines the Frame Type
to be STS-3c (SONET) or STM-1 (SDH).
DS3 Mapping (Default - Direct); options: Direct, PLCP-Ext' 8Kclk, PLCP-Int' 8Kclk
This parameter is only used in T3 card. It selects the DS3 mapping and the
PLCP clock, in case of PLCP mapping. Direct mode is the HEC mapping
mode. PLCP mapping with Internal 8Kclk forces the transmit PLCP to be
synchronized to an on-board clock. PLCP with External 8Kclk uses the
received PLCP clock as a reference.
ASCII Terminal
Configuration To set ASCII terminal parameters, select option 4 from the Configuration
menu.
ASCII TERMINAL CONFIGURATION
1. Display Mode: Color
2. Baud Rate: 9600 Kbps
ESC. Exit
Select item from the menu:
Note When you change the module's baud rate, you will lose communication with
the module, until you adjust the baud rate of ASCII terminal or PC to match
the baud rate of the module.
The default display mode is Color. The default baud rate is 9600.
To change the baud rate:
1. Set the required baud rate on the ARC-101 monitor (option 2 in the
ASCII terminal configuration window).
2. Press the Escape key (ESC).
3. Change the ASCII terminal baud rate.
4. A "Press ESC" message will appear on the monitor while synchronization
is achieved.
