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 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 an ROM in
socket U133.

As with the other interface processors, the enabled LED is on when the HIP is enabled for operation.
The four LEDs above the HSSI port (see Figure 1-21) indicate the following:

High-Speed Serial (HSSI) Interface Processor (HIP)
RT (Receive Timing)—When on, indicates that the HIP has detected a receive clock signal.
During normal operation, this signal is received from the external DSU. During loopback, this
signal is generated internally.
RD (Receive Data)—On when the HIP detects packet traffic and indicates that the HIP is able to
receive packets from the external DSU.
ST (Send Timing)—On when the HIP is sending a transmit clock signal to the external DSU.
During normal operation, this signal is derived from the receive timing (RT) signal from the
external DSU. During loopback, this signal is generated internally.
C (Connected)—When on, indicates normal operation; the HIP is properly connected to the
external DSU, and TA (DTE available) and CA (DCE available) are active. This LED is off when
the HIP is in loopback mode and when it is not connected to the DSU.
