8-8 Cisco BPX 8600 Series Reference
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.
