The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Clas s A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruc tion m anual , may cause harm ful inte rfere nce to radio co mmuni cat ions . Operati on of thi s equipment in a reside nt ial area i s li kel y t o cause har mful interferenc e, i n whi c h ca se u sers will b e req uired to correct the interf e rence at th eir own expense.

The following information is for FCC complia nce of Cl ass B devices: The equ ipment de scribe d in thi s manu al genera tes and m ay radiate radio-freque n cy energ y. If it is not insta l led in acc orda nc e wit h C isc o’s instal lat io n inst ruc tion s, it ma y ca us e int erf ere nc e wi th rad io and tel evision reception. This equipmen t has bee n tested a nd found to compl y with th e lim its for a Clas s B digit al device in acc ordance with the specifications in part 15 of the FCC rules. These spe cifications are designe d t o provide reason able pr otec tion a gainst such i nterfere nce in a residential installation . However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cis co’s written authoriza tion may resu lt in the equipme nt no longe r compl ying with FCC requi rement s for Cl ass A or Class B digital devices. In that event, your righ t to use the equipme nt may be limit ed by FCC regulati ons, and you may be required to correct any interference to radio or television com munica tions a t your own expense.

You can determine whether your e quipme nt is caus ing inte rfere nce by turning i t off. If the inte rfere nce sto ps, it was pr obably caused by the Cisco equipment or one of its periphe ral devices. I f the equip ment c auses interferenc e to ra dio or tel evision recept ion, try to corre ct the interference by using one or more of the following meas ures :

• Turn the television or radio antenna until the interf erenc e stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits control led by different circuit bre akers or fuse s.)

Using the DPA 7630/ 76 1 0, yo u c a n integra t e the following s ystems:

• Cisco CallManager 3.1(1) or higher

• Octel 200 and 300 voice messaging systems (using APIC/NPIC integration)

• Skinny Client Control Protocol (SCCP)—enables communication between

the DPA 7630/7610 and Cisco CallManager.

• Network Time Protocol (NTP)—enables synchronization of time and date

Network Management Protocols

The DPA 7630/7610 supports Simple Network Management Protocol (SNMP) and implements several industry-standard Management Information Bases (MIBs).

Understanding SNMP Support

The DPA 7630/7610 (with software version 1.1 or higher) supports SNMP versions 1 and 2, enabling you to perform the following commands:

• Get—Retrieve a specific node’s value.

• GetNext—Retrieve the first value present in the ordered tree whose node

succeeds th e o ne specifie d.

• GetBulk—Retrieve bounded number of values whose nodes succeed, in the

numeric al or de ring , th e on e spec ified. Get Bu lk is availa ble onl y in SNMP v2.

• Set—Set a specific valu e.

Understanding Supported MIBs

The DPA 7630/7610 supports the following MIBs.

RFC 1213

RFC 1213 is the basic MIB 2 specification which indicates the state of network interface s an d stat is t ics for netw o rk p r ot oc ol s .

The DPA 7630/7610 supports RFC 1213 on the Ethernet interface with the followi ng cavea ts :

• The digital telephony interfaces are not listed in the ifTable.

• ifAdminStatus cannot be written, and it is fixed at “up”.

• ifLastCha nge ret urn s as “0”.

• ifSpecific returns as “0 , 0 ”.

• atTable can no t be w r itt en .

• No “ip***” values can be written.

• You cannot write to “tcpConnState” for an active TCP connection.

• The DPA 7630/7610 does not implement the External Gateway Protocol

(EGP).

RMON

The DPA 7630 /7610 impleme nts the Et hernet Statis tics gro up in Remo te Netw ork Monitori ng ( RM O N ) , with the excep t io n of “E therStatsS ta tu s .” Th is is fixed at “valid” and ca nn o t b e w r it te n.

Cisco CDP MIB

Cisco D is c ove r y P ro to c o l (CDP) is a meth od that Cisco devices us e to adver tise their presence and to discover information about other nearby devices. The DPA 7630/7610 implements all objects in this MIB with the exception of “cdpGlobalRun”. This object returns “true” when read, and cannot be written using S N MP.

Cisco Process MIB

This MIB describes the processes currently running on the device. However, because the DPA 7630/7610 has threads, rather than processes, running on it the MIB is implement ed w ith the following caveats:

• The amount of memory allocated is not recorded on a per-thread basis.

Therefore, cp mP roc Ex tM emAllocated and cpmPro cEx tM e m Fre ed are returned as 0.

• All threads run at the same priority. Therefore, for every process

cpmProc E x tPr iority wil l be returned as “no rmal.”

• It is not possible to change a process’s priority so attempts to write

“cpmProcEx tP r ior it y” ar e u n suc cess f u l.

Calista DPA MIB

The DPA 7630/7610 supports an additional DPA-specific Cisco MIB in version

1.2(1 ) and late r. The MIB O ID is : For an explanation of this MIB, refer to the SNMP v2 MIBs available at the

Understanding How the DPA 7630/7610 Works

The Cisc o DPA 7630/7610 ena ble s yo u t o in te grat e you r e xi sti ng Octe l v o ice ma il with Cisco CallM anager and ei th er a D efinity PBX system or a Mer id ia n 1 PBX system. If you have a Definity PBX, use the DPA 7630; if you have a Meridian 1 system, use the DPA 7610.

The DPA 7630/7610 functions by emulating digital phone or PBX systems. This capabilit y allows it to appear like th es e devi ces to Cisco CallM an ag er, Oc te l, Definity, and Meridian 1 systems.
