Multichannel Interface Processor (Mip) - Cisco 7000 Series Hardware Installation And Maintenance Manual

For complete descriptions of the LED states, refer to the appendix "Reading LED Indicators."
The HIP interface port is a 50-pin, SCSI-II-type receptacle. You need a HSSI interface cable to
connect the HIP with an external DSU. Although the HSSI port and cable are physically similar to
SCSI-II format, the HSSI specification is more stringent than that for SCSI-II, and we cannot
guarantee reliable operation if a SCSI-II cable is used.
A null modem cable allows you to connect two collocated routers back to back to verify the
operation of the HSSI interface or to build a larger node by linking the routers directly. For a
description of HSSI network and null modem connections, refer to the section "HSSI Connections"
in the chapter "Installing the Router." The appendix "Cabling Specifications" provides connector
pinouts and cable assembly drawings.
The Cisco 7010 supports up to three HIPs for a total of three HSSI interfaces. There are no
restrictions on slot locations or sequence; you can install a HIP in any available interface processor
slot.

MultiChannel Interface Processor (MIP)

The MIP provides up to two channelized E1 or T1 connections via serial cables to a channel service
unit (CSU). On the MIP, two controllers can each provide up to 24 virtual channels. Each virtual
channel is presented to the system as a serial interface that can be configured individually.
The MIP, shown in Figure 1-22, provides two controllers for transmitting and receiving data
bidirectionally at the T1 rate of 1.544 Mbps (in a future version at the E1 rate of 2.044 Mbps). For
wide-area networking, the MIP can function as a concentrator for a remote site.

microcode
There are no restrictions on slot locations or sequence; you can install a MIP in any available
interface processor slot. The MIP is compatible with any Cisco 7000 series router that is operating
with the following software and microcode:
•
The system software is Cisco IOS Release 10.0 or later.
•
The microcode version is Release 1.4 or later.
Refer to the appropriate software configuration and command reference publications for specific
configuration information.
Note
MIP ports and up to 180 serial interfaces.
