This screen shows parameter of system capacity when use 4/8/16E1 service card. The options are
shown as rates such as 4x2M, 8x2M and 16x2M. And the RF bandwidths are 7MHz for 4x2M, 14MHz
for 8x2M and 28MHz for 16x2M.
The link will be lost, if the rates are different between local and remote. At this time, the link is
recovered when set the local rate to the rate as same as remote. The rates are stored in EEPROM.
This screen shows tow parameters of system capacity when use 10/100BASE-T+1/2/4E1 service
card. The first parameter is the option for using E1 tributaries. The second parameter is the option LAN
capacity.
The E1 avalible capacity is 0x2M, 1x2M, 2x2M and 4x2M.
The LAN avalible capacity is based n*2M. The active rate of 2M is 2.112Mbps, i.e. n=5, the LAN
capacity is 10.56Mbps.The LAN rate will be selectable with 8E1(14MHz RF bandwidth) and
16E1(28MHZ RF bandwidth),i.e. if E1 capacity is 2x2M, then the LAN capacity can be set to 12M or
28M.
The following steps may be operated for changing these parameters.
• Use the
keys on the IDU to select E1 menu, press ENT.
• Use the
and _keys on the IDU to select the E1 required capacity. The avalible capacity
is 0x2M, 1x2M, 2x2M and 4x2M.
• Press ENT to set the E1 capacity, and the LAN capacity will auto change.
• The IDU will display the new setting.
• Use the
keys on the IDU to select LAN menu, press ENT.
• Use the
and keys on the IDU to select the LAN required capacity.
• Press ENT to set the LAN capacity.
• The IDU will display the new setting.
