Maximum speed for single E1 channel is 2.048 Mbps and for single T1 channel is 1.544 Mbps.
The actual/total E1/T1 channels speed is auto-detected by the system and is displayed in
Config  Ports  MUX section.
Up to 4 EMM modules can be connected into the cascade and thus get the maximum quantity
of external ports (E1/T1 EMM and ASI EMM modules combination is possible). Maximum 4
EMM modules can be cascaded and in case of E1/t1 EMM modules the maximum count of
E1/t1 channels is 64. SFP 1000Base-SX on the left side SFP 2 UPLINK 2 is dedicated for the
modules interconnection into cascade. The configuration of all EMM modules is performed
from the web GUI of the IDU.
E1/T1 EMM extension module has following interfaces/connectors:

Primary SFP port reserved for connection to the IDU or to primary EMM extension module in
EMM extension module chain.
SFP 2 UPLINK 2
Secondary SFP port reserved for connection to secondary / next EMM extension module in
EMM module chain or for connection to relay IDU in add/drop configuration.
