2.5 Speed
All E1 lines consist of 31 channels (timeslots) that continually run at 64 kbps for a collective
bandwidth of 1,984 kbps. Timeslot configuration dictates how many of the channels for each port
will actually receive data. Ports configured to operate as fractional E1 lines require contiguous
timeslots as indicated in the chart below.
3.0 ADDITIONAL INFORMATION
3.1 Configuration and Management
Once the EIM2000 has been installed, all parameter settings are software selectable via Command
Line Interface (CLI), Simple Network Management Protocol (SNMP) and/or Net to Net's Network
Management System (NMS) dependent upon the multiplexer uplink module (MUM) model installed
in your IP DSLAM. Refer to Net to Net's NMS Management User Guide
(
http://www.nettonet.com/support/docs/210-0000048
) and/or CLI Management User Guide
(
http://www.nettonet.com/support/docs/210-0000052
) for further instruction regarding IP DSLAM
management and interface module parameter configuration.
3.2 Data Storage
Upon initial power up of the IP DSLAM, default parameters of the EIM2000 will remain in place
unless changed via NMS, CLI or SNMP. Once changed, new configurations will automatically be
recorded in both the Random Access Memory (RAM) of the EIM2000 and the Non-Volatile Random
Access Memory (NVRAM) of the MUM. While data stored in EIM2000 RAM will be erased if the
module is removed from the IP DSLAM, or the IP DSLAM loses power, interface module data stored
within MUM NVRAM will remain intact (even if the chassis loses power) unless deliberately cleared or
reconfigured.
3.3 European Regulatory Compliance
This Class A product complies with European Norm EN55022.
