DTE Interface
The ASM-61 DTE interface is an Ethernet/Fast Ethernet port with VLAN support.
The plug-and-play 10/100BT interface uses on-chip autonegotiation algorithm to
configure itself automatically for 10 Mbps or 100 Mbps half- or full-duplex
operation.
Management
Operating with the constant line rate and preset timing modes, ASM-61 does not
require any user configuration.
Timing
ASM-61/CO operates with internal clock, and ASM-61/CPE uses clock received
from the line.
Synchronization
ASM-61 units reach synchronization in about 15 seconds at cold restart (power-on)
and in less than one second at warm restart.
Test Capabilities
ASM-61 performs an extensive self-test at start-up. During the self-test, ASM-61
checks its CPU, internal framer, DTE/line interfaces and power supply.
