Product Features SPID and Switch Automatic Detection The automatic service profile identifier (SPID) and switch detection simplifies the use of ISDN terminal equipment and makes the equipment easier to use with fewer parameters to enter. With this feature, you only enter the local directory numbers with area code; no SPID number or switch type is required. The automatic detection feature only applies to ISDN switches for the USA and Canada, usually an AT&T 5ESS Custom, DMS-100, NI-1, or NI-2 switch. The automatic detection mechanism might not work with any other switch, such as a Siemens switch. The automatic detection feature is only implemented in the U. S. image. Bandwidth Allocation Control Protocol and Bandwidth Allocation Protocol The Bandwidth Allocation Control Protocol (BACP) and the Bandwidth Allocation Protocol (BAP) define a set of rules to control dynamic bandwidth allocation to coordinate and negotiate the actual allocation and deallocation of the second channel. NetBIOS Name Spoofing If spoofing is set, the router keeps a local database of up to 100 Domain Name System (DNS) name entries and has an aging scheme to age out the unused name entries. When a WINS client sends out a NetBIOS Name query, the router can attempt to answer the query in place of the WINS server. If the router cannot answer, the router forwards the query packets to the server, which provides the response to the client. DHCP Server and Relay Agent DHCP automates IP addressing and reduces the number of IP addresses a site might require. Cisco 700 series routers can function as a dynamic host configuration protocol (DHCP) server. Cisco 700 series routers can also function as a DHCP relay agent, but the router cannot act as a DHCP server and a relay agent at the same time. When configured, your router can relay DHCP requests and responses between DHCP clients and a specified DHCP server. 1-4 Cisco 700 Series Router Installation Guide

SPID and Switch Automatic Detection
The automatic service profile identifier (SPID) and switch detection simplifies the use of
ISDN terminal equipment and makes the equipment easier to use with fewer parameters to
enter. With this feature, you only enter the local directory numbers with area code; no SPID
number or switch type is required.
The automatic detection feature only applies to ISDN switches for the USA and Canada,
usually an AT&T 5ESS Custom, DMS-100, NI-1, or NI-2 switch. The automatic detection
mechanism might not work with any other switch, such as a Siemens switch. The automatic
detection feature is only implemented in the U. S. image.
Bandwidth Allocation Control Protocol and Bandwidth Allocation
Protocol
The Bandwidth Allocation Control Protocol (BACP) and the Bandwidth Allocation
Protocol (BAP) define a set of rules to control dynamic bandwidth allocation to coordinate
and negotiate the actual allocation and deallocation of the second channel.
NetBIOS Name Spoofing
If spoofing is set, the router keeps a local database of up to 100 Domain Name System
(DNS) name entries and has an aging scheme to age out the unused name entries. When a
WINS client sends out a NetBIOS Name query, the router can attempt to answer the query
in place of the WINS server. If the router cannot answer, the router forwards the query
packets to the server, which provides the response to the client.
DHCP Server and Relay Agent
DHCP automates IP addressing and reduces the number of IP addresses a site might
require. Cisco 700 series routers can function as a dynamic host configuration protocol
(DHCP) server.
Cisco 700 series routers can also function as a DHCP relay agent, but the router cannot act
as a DHCP server and a relay agent at the same time. When configured, your router can
relay DHCP requests and responses between DHCP clients and a specified DHCP server.
