4.3 Intelligence Service UnitISU
4.3.1 Overview
The ISU board is the intelligence service unit. It serves as a broadband remote access
server (BRAS), which performs authentication, authorization and accounting (AAA)
on subscribers.
The ISU board provides two GE optical ports and eight FE electrical ports.
The ISU board is of two types: ISUA and ISUE. The difference between them is that
the lower subboard port of the ISUA board can hold only the FE optical subboard,
while the lower subboard port of the ISUE board can hold only the 4-port FE electrical
subboard.
The ISU board resides in slots 14 and 15 of the MA5600 service frame. One service
frame can hold up to two ISU boards working in the active/standby mode.
4.3.2 Front Panel
The ISUA and ISUE boards share the same front panel, except that the silkscreens of
the board names are different.

4.6.4 DIP Switches of Subboard
The E8IT subboard (IMA service subboard) is of two types: E8IT.2 REV.0 and E8IT.2
REV.A.
The E8IT.2 REV.0 subboard supports only the 75-ohm coaxial cable.
The E8IT.2 REV.A subboard supports both the 75-ohm coaxial cable and the
120-ohm twisted pair by setting the DIP switches.
Both types of E8IT subboards have five sets of DIP switches (S1S5), where,
S5 has four bits.
S1, S2, S3, and S4 have eight bits each.
The port impedance of the E8IT.2 REV.0 is 75 ohms by default, you need not
configure it.
Table 4-14describes the settings of DIP switches.
