Chapter 4. Software Management ARC-101 Installation & Operation Manual
4-4 Configuration Window
The options are 25%, 50%, 75%, 90% and 100%.
EFCI Marking (Default - Disable); options: Enable, Disable
Enables EFCI marking while FIFO is in congested state. Setting this
parameter to Enable causes the EFCI marking of all cells that are received,
while FIFO is in a congested state.
CLP Dropping (Default - Disable); options: Enable, Disable
Enables CLP dropping when FIFO is congested. Setting this parameter to
Enable causes cells - with CLP bit set - to be dropped, if they are received
while FIFO is in a congested state.
Early Packet
Discard (Default - Disable); options: Enable, Disable
Enables entire frame, except for last cell, to be dropped when FIFO is
congested. Setting this parameter to Enable causes frames to be dropped, if
they are received while FIFO is in a congested state.
Right/Left
Module
Configuration The two windows (Left and Right module configuration, options 2 and 3 in
the Configuration menu) are identical.
LEFT MODULE
1. Port Enable/Disable: Enable
2. Transmit Clock Source: Loopback
3. Loopback State: Disable
4. SONET/SDH Frame Type: STM-1 (SDH)
ESC. Exit
Port Enable/Disable (Default - Enable); options: Enable, Disable
If the port is Disabled, no data will be received at the port. Transmit
functions are not changed. Remote loop is still available. If the port is
Enabled, received data is transferred to the other port.
Transmit Clock
Source (Default - Local timing); options: Local timing, Loopback timing
This parameter selects the clock source for the transmit clock. "Local timing"
selects the clock that is derived from the oscillator on board. "Loopback
timing" selects the clock recovered from the received data to be the source.
Note that for an E1 interface, the default is "Loopback timing" and should
not be changed. Do not configure the module for Loopback timing while it
is in Internal Loopback mode.
