CLUES	SOLUTION

ACROSS
1	A network which provides some redundancy.
10	SS7 (signaling system 7) feature in which a series of digits, either analog or digital, are included in the call, identifying the telephone number of the calling device.
11	An interface that allows the user to interact with the operating system by entering commands and optional arguments.
12	OSI RPC mechanism used by various OSI network application protocols.
13	On the fly.
15	A set of rules that describe how a Web server communicates with another application running on the same computer and how the application communicates with the Web server.
16	Chips that can be erased using electrical signals applied to specific pins.
19	Entity that issues digital certificates (especially X.509 certificates) and vouches for the binding between the data items in a certificate.
20	ATM Forum specification for distributing topology information between switches and a cluster of switches that is used to compute paths through the network. The specification is based on well-known link-state routing techniques and includes a mechanism for automatic configuration in networks in which the address structure reflects the topology.
21	CSMA/CD topology that operates at 100Mbps.
23	Part of an SS7 MSU that acknowledges the receipt of signal units by the remote signaling point. Contains the sequence number of the signal unit being acknowledged.
25	OSI network management protocol created and standardized by ISO for the monitoring and control of heterogeneous networks.
28	Establishes and maintains the routing information that is required to route datagrams from any source socket to any destination socket in an AppleTalk network.
30	An information element.
31	Aids in the automatic creation of Fast EtherChannel links.
32	A network that extends remote access to a private network using a shared infrastructure.
34	EIA/TIA-232 interface circuit that is activated when DCE is powered up and ready for use.
35	a measure of data transfer.
38	Nonrouting host or node in an OSI network.
39	_ _ _ Identifier is used by frame relay to route traffic.
40	The maximum amount of data (in bits) that a Frame Relay internetwork is committed to accept and transmit at the CIR.
41	Technique supported by BGP4 and based on route aggregation. Allows routers to group routes together to reduce the quantity of routing information carried by the core routers.
43	An address that is permanently affixed to a network interface card.
44	Means by which an application program talks to communications software. Standardized APIs allow application programs to be developed independently of the underlying method of communication.
45	A byte returned by the Cisco VCO/4K to the controlling host to indicate the successful completion or error status of command processing.
46	Cisco Group Management Protocol (CGMP)/Internet Group Management Protocol (IGMP) messages and GARP Multicast Registration Protocol (GMRP) messages are collectively known as ________ messages.

DOWN
1	Device used to connect simple devices (like character-mode terminals) that do not support the full functionality of a particular protocol to a network. Buffers data and assemble and disassemble packets sent to such end devices.
2	In ATM, an address that can be shared by multiple end systems.
3	Connection of two or more stations in a logically circular topology.
4	Cisco system that implements enterprise-wide call distribution across call centers
5	A dual-wide port adapter for the Cisco 7200 router. It is ABR-ready and supports traffic shaping.
6	Purchased right to transmit RF waves over a given BTA for typically periods of 10 years.
7	In ATM, an RM cell used to limit the ACR for a transmission to a specific value.
8	Devices used at a home or a small office.
9	Network standard for high-speed (up to 52 Mbps) serial connections over WAN links.
14	_ interface.
17	Multicast routing architecture that allows the addition of IP multicast routing on existing IP networks.
18	Made of 6 frequencies that provide 15 two-frequency combinations for indication digits 0 through 9 and KP/ST signals.
19	QoS class defined by the ATM Forum for ATM networks. It is used for connections that depend on precise clocking to ensure undistorted delivery.
22	The E in EFCI stands for _
24	SNA message consisting of a series of vectors conveying network management specific information.
26	A framework of open standards that provides data confidentiality, data integrity, and data authentication between participating peers.
27	Research and development center operated by XEROX.
29	A measure of data transfer.
30	Network element that can be provisioned from a remote OSS.
33	A measure of Lost stable (connected call) or non-stable (call being setup) call due to any hardware or software failure, procedural error, or other causes.
34	A device that connects many digital subscriber lines to a network by multiplexing the DSL traffic onto one or more network trunk lines.
35	Mechanism used to abate congestion.
36	OSI link-state routing protocol.
37	Mechanism to identify a failure that has occurred at the far end of the network.
40	rate of data transfer.
42	A base 10 logarithmic scale.
44	The response packet from a RADIUS server notifying the access server that the user has been authenticated. This packet contains the user profile, which defines the specific AAA functions assigned to the user.
