Matrix ETERNITY Quick Start 41
• By default J5 is set to BC position to provide 120 termination resistance for E1
connectivity.
• To set 100 termination resistance for T1 connectivity, set jumper J5 to AB
position.
In ETERNITY PE
Termination Resistance of the PRI Port for T1 or E1 Connectivity is set by changing
the position of the Jumper J2 as given in the table below:
By default the jumper J2 is in BC position to provide 120 for E1 connectivity.
To se t 1 0 0 termination resistance for T1 connectivity, set jumper J2 to AB position.
• Connect one end of the RJ45 cable provided with the T1E1PRI Card of
ETERNITY ME/GE/PE to the T1E1 Port and the other end to the modem
provided by the ISDN Service Provider.
