Extended Services Processor

Extended Services Processor

The Extended Services Processor (ESP) is an adjunct processor shelf integrated into the BPX switch.

The basic ESP features include:

•

•

•

140 MIPS CPU, with a 143Mhz clock

128 Megabytes of memory

4 Gigabyte hard disk

Available in either AC- or DC-powered models (ESP-AC or ESP-DC), the ESP is an orderable option for the BPX switch. The ESP can be configured in both non-redundant and redundant configurations. For the redundant configuration, two ESPs are installed in the BPX switch.

ESP Interfaces

The ESP uses three main physical interfaces, as shown in Figure 8-5:

•Terminal port for the direct connection of a terminal, such as a VT-100, to provide access for local configuration and to act as a console.

•10Base-T Ethernet port for connection to the Cisco StrataView Plus Workstation and to the BPX switch. Telnet or XTERM sessions can be established through the Ethernet port, and perform the same functions as can be performed with a directly connected terminal.

•ATM Network Interface Card (ATM NIC) for connection to the BPX switch. The ATM NIC is typically connected to a BPX switch BXM card using OC-3 multimode fiber connection with SC connectors. There are optional cables with built-in optical attenuation that allow BXM single mode fiber (SMF) backcards to be connected to the ESP ATM NIC.
