DB-25
AC power supply DB-25 alarm connector—A female DB-25 D-sub connector which enables you to
attach an external alarm monitoring facility to the router, thus supporting a telco-style of handling
alarm conditions in the router.
Data communication equipment. Provide clocking to DTE. Console port of UART.
DCE
Double Data Rate—Data transfer method that transfers data on both clock edges.
DDR
Double Data Rate Synchronous DRAM
DDR-SDRAM
Data Encryption Standard algorithm
DES
Dynamic Host Configuration Protocol
DHCP
A command mode in Cisco IOS XE where all the commands stored in the non-RPIOS sub-package are
Diagnostic mode
still accessible. All commands available in diagnostic mode are also available in privileged EXEC
mode.
Date Terminal equipment. Auxiliary ports of a UART.
DTE
Dual Asynchronous Receiver/Transmitter. Used for the CONsole serial port.
DUART
E
Enhanced SerDes Interconnect—Four serial links, each at 1.25-3.125 Gbps, 24b/26b. These are the
ESI
datapath links on the midplane connecting the RP, SIPs, and standby ESP modules to the active ESP.
Event-based flow control – packet-based protocol over SPA-SPI interface used by newer high-channel
EBFC
count, variable rate SPA's such as ATM to pass egress queue status deltas to the host.
Extended flow control – calendar-based interface used by high-channel count SPA's to pass egress
EFC
queue status to the host.
Typical traffic pattern including voice for a typical enterprise environment with a mix of packet sizes
EMIX
and with an average packet size of 250 bytes.
Ethernet Out of Band Channel—Used for communication between the control processors on the Cisco
EOBC
ASR 1000 chassis
Cisco ASR 1000 Series Embedded Services Processor. The ESP handles forwarding plane traffic and
ESP
performs packet processing functions such as Firewall inspection, ACLs, encryption and QoS. Note
that the Cisco ASR1000-ESP is also referred to as the forwarding processor in this document.
ASR1000rp1-espbase.pkg. Provides the ESP operating system and control processes, and the ESP
ESPBase
software.
This is the QFP client that provides a framework for mapping edge switching services feature data from
ESS
the control plane into QFP data plane data structures.
Event-based flow control - interface used for chip-to-chip communication of the status of egress
EV-FC
queues, used on the embedded services processor
