ETRM01-NMC
Network Management Card
This single slot card is installed in the first slot of the
chassis. The card has an RS-232 serial port on a DB9 female
connector for connection of any standard dumb terminal for an
easy menu driven configuration. The RJ-45 jack is a 10/100
Ethernet connector for IP based management. The NMC card
supports a remote Telnet Web GUI management with the
same user friendly interface as local console. NMC can be
used by compiling the enterprise MIB into your favorite
network management software.
ETRM01-FTEC
E1,T1 Cross-Rate Converter
The ETRM01-FTEC is E1,T1 cross rate card. The time slot
cross connect enables the conversion between one T1 signal
and one E1 signal. T1 and E1 signals with frames employ
u-Law and A-Law compander encoding principles respectively
and encode those analog signals into 64kbits digital data. The
E1 interface supports CCS (PCM31)or CAS (PCM30) frames
with or without CRC-4 and with HDB3 line coding. The T1
interface supports D4 or ESF frame formats with B8ZS or AMI
line code. Multiple clock source selection provides maximum
flexibility in connecting both T1 and E1.
