Interface standards
802.3, 802.3u, 802.3ab
Interface type
Auto MDI/MDI-X
Supported frame format
•
Ethernet_II
•
Ethernet_SNAP
Transmission distance
100 m (328.08 ft)
Interface speed and duplex
mode
10 Mbps
Full/half duplex, auto-negotiation
100 Mbps
Full/half duplex, auto-negotiation
1000 Mbps
Full duplex
NOTE:
•
The MDI standard is typically used on the Ethernet interface of network adapters; the MDI-X
standard is typically used on hubs or LAN switches.
•
When 10/100 Mbps and half duplex/full duplex are specified for an Ethernet copper port, the
Ethernet copper port operates in forced mode. When 1000 Mbps is specified or the interface
speed and the duplex mode are not simultaneously specified for an Ethernet copper port, the port
operates in auto-negotiation mode.
•
An Ethernet copper port supports auto MDI/MDI-X in both forced or auto-negotiation mode.
Interface cables
A MIM-2GBE uses a category-5 straight-through or crossover Ethernet cable when operating at
10/100 Mbps and uses a category-6 cable (recommended) when operating at 1000 Mbps. For the
appearance and connection of a MIM-2GBE interface cable, see "

MIM-8E1(75)/MIM-8E1(75)-F
The MIM-8E1(75) is an 8-port channelized E1 interface module, which transmits, receives, and
processes eight channels of E1 data, and supports CE1 access.
The MIM-8E1(75)-F is an 8-port non-channelized E1 interface module. It differs from the
MIM-8E1(75) in these ways:
•
The FE1 operating mode supported by the MIM-8E1(75)-F allows only one n × 64 kbps bundle
to be formed on each interface, where n = 1 to 31.
•
The MIM-8E1(75) allows arbitrary grouping of 31 channels and thereby multiple bundles.
