Hssi Interface Processor (Hip) - Cisco 7000 Hardware Installation And Maintenance

Figure 1-20 shows the 15-pin port and the label that indicates either balanced or unbalanced mode.
Figure 1-20
The FSIP end of all E1-G.703/G.704 adapter cables is a 15-pin D-shell connector (DB-15). At the
network end, the adapter cable for unbalanced connections uses a BNC connector. The adapter
cables for balanced mode are available with several connector types to accommodate connection
standards in different countries.
You must use the proprietary cables to connect the E1-G.703 port to your network. Cables for
balanced and unbalanced mode are available with the following types of network-end connectors:
•
Balanced (120-ohm) twinax split at the network end, with separate transmit and receive cables,
each with a BNC connector
•
Balanced (120-ohm) cable with a DB-15 connector at the network end
•
Unbalanced (75-ohm) coax with BNC connectors at the network end (used primarily for
connection in the United Kingdom)
In addition to these cables, some connections require bare-wire connections (directly to terminal
posts).
Table 1-5 lists the model numbers and descriptions of the E1-G.703 port adapters and cables.

HSSI Interface Processor (HIP)

The HIP, shown in Figure 1-21, provides a full-duplex synchronous serial interface for transmitting
and receiving data at rates of up to 52 Mbps. The High-Speed Serial (HSSI) interface, recently
standardized as EIA/TIA 612/613, provides access to services at T3 (45 Mbps), E3 (34 Mbps), and
SONET STS-1 (51.82 Mbps) rates. The actual rate of the interface depends on the external data
service unit (DSU) and the type of service to which it is connected. The default HIP microcode
resides on a ROM in socket U133.
As with the other interface processors, the Enabled LED lights to indicate that the HIP is enabled for
operation. The four LEDs above the HSSI port (see Figure 1-21) indicate the following:
