Release Notes for the Cisco ICS 7750 for Cisco IOS Release 12.2(2)XK
October 18, 2001
Cisco IOS Release 12.2(2)XK introduces support for connections between Cisco CallManager (running on system processing engine [SPE] cards) and analog station interface (ASI) cards and multiservice route processor (MRP) cards in the Cisco Integrated Communications System (ICS) 7750, using the Media Gateway Control Protocol (MGCP).
Note
Cisco IOS Release 12.2(2)XK on the Cisco ICS 7750 supports MGCP on analog interfaces only. MGCP support on digital interfaces on the Cisco ICS 7750 will be available in a later release.

Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features. Release 12.2(2)XK supports the same feature sets as Releases 12.2 and 12.2T, but Release 12.2(2)XK can include new features supported by the Cisco ICS 7750 platform. Table 6 lists the feature sets supported by the Cisco ICS 7750.

New and Changed Information
The following sections list the new features supported by the Cisco ICS 7750 series for Cisco IOS software releases Release 12.2(2)XK.
New Hardware Features in Release 12.2(2)XK2
Cisco IOS Release12.2(2)XK2 on the Cisco ICS 7750 supports the following new hardware features:
•
•
•
•
Two-Port FXO for The United States With Battery Reversal (VIC-2FXO-M1)
The Cisco ICS 7750 now supports two-port Foreign Exchange Office (FXO) voice interface cards for the United States using the battery reversal VIC-2FXO-M1 card. The Cisco FXO interface is an RJ-11 connector that allows an analog connection to be directed at the PSTN central office or to a station interface on a PBX. The FXO is on the switch end of the connection and plugs directly into the line side of the switch, so the switch perceives the FXO interface as a telephone. FXO-M1 is an enhancement of FXO with battery reversal and Caller ID features.
Two-Port FXO for Europe with Battery Reversal (VIC-2FXO-M2)
The Cisco ICS 7750 now supports a two-port Foreign Exchange Office (FXO) voice interface card, VIC-2FXO-M2, for Europe. VIC-2FXO-M2 is an enhancement of the VIC-2FXO-EU card, with battery reversal and Caller ID features.
Two-Port FXO for Australia with Battery Reversal (VIC-2FXO-M3)
The Cisco ICS 7750 now supports a two-port Foreign Exchange Office (FXO) voice interface card, VIC-2FXO-M3, for Australia. VIC-2FXO-M3 provides battery reversal features.
Two-Port Direct Inward-Dialing Voice Interface Card (VIC-2DID)
The Cisco ICS 7750 now supports the two-port, DID voice interface card (VIC-2DID). DID is a service offered by telephone companies that enables callers to dial directly to an extension on a Private Branch Exchange (PBX) or packet voice system (for example, Cisco CallManager and IOS routers or gateways) without the assistance of an operator or automated call attendant. This service uses DID trunks, which forward only the last three to five digits of a phone number to the PBX, router, or gateway. For example, if a company has the phone extensions 555-1000 to 555-1999, and a caller dials 555-1234, the local central office (CO) forwards 234 to the PBX or packet voice system. The PBX or packet voice system then rings extension 234. The entire process is transparent to the caller.
The VIC-2DID card services two analog DID trunks using analog voice or fax. The card provides dual-working modes, DID and FXS, which are mutually exclusive.
New Software Features in Release 12.2(2)XK
Cisco IOS Release12.2(2)XK on the Cisco ICS 7750 supports the following new features:
•
•
MCGP Control of Analog Interfaces
Media Gateway Control Protocol (MGCP) and Simple Gateway Control Protocol (SGCP) are call control protocols that run between call agents (CA) and gateways in a packet telephony network.
As in the earlier implementations of the two protocols, a gateway handles the translation between audio signals and the packet network. These gateways interacts with a CA, also called a Media Gateway Controller (MGC), which performs signal and call processing on the gateways' calls.
On the Cisco ICS 7750, MRP and ASI cards can provide an interface between analog (RJ11) calls from a telephone and the VoIP network. This feature supports analog (POTS) calls for both SGCP and MGCP on the Cisco ICS 7750.
DTMF Relay
DTMF uses specific pairs of frequencies within the voice band for signaling. Over a 64-kbps pulse code modulation (PCM) voice channel, these signals can be carried without difficulty. However, when using a low-bit-rate codec for voice compression, the potential exists for DTMF signal loss or distortion. Using an out-of-band signaling method for carrying DTMF tones across a VoIP infrastructure provides an elegant solution for these codec-induced symptoms.
Supplementary Services
When MGCP is used, Cisco CallManager controls routing and tones and provides supplementary services to the gateway (MRP or ASI card). MGCP provides call preservation (calls are maintained during failover and failback), redundancy, dial plan simplification (no dial peer configuration is required on the gateway), hookflash transfer, and tone on hold. MGCP-controlled gateways do not require an MTP to enable supplementary services such as hold, transfer, call pickup, and call park.
Caller ID
The Cisco ICS 7750 supports Caller ID functions on analog FXS, FXO-M1, and FXO-M2 voice interfaces, and on the FXS mode of the Direct Inward Dialing (DID) voice interface card, VIC-2DID.
Caller ID (sometimes called CLID for calling line identification) is an analog service offered by a Central Office (CO), which supplies calling party information to subscribers. Typically, the calling party number and the name appears on a station (also called extension) device such as a PC telephony software application screen or the display on a telephone. Type 1 Caller ID provides the calling party information while the call is ringing, and Type 2 Caller ID provides the additional convenience of calling number display while the recipient is on another call. In this release, only Type 1 Caller ID is supported.
Modem Pass-Through Using H.323
Modem pass-through over VoIP provides for the transport of modem signals through a packet network by using pulse code modulation (PCM)-encoded packets.
Modem pass-through performs the following functions:
•
•
•
•
•
Modem pass-through offers the following benefits:
•
•
•
•
Fax Pass-Through Using H.323
The Cisco ICS 7750 allows you to pass through fax signals on one line at a time. To use the fax pass-through feature, the gateway must be configured to detect the fax tone and switch codec.
Note
Important Notes
The following sections contain important notes about Cisco IOS-related issues that can apply to the Cisco ICS 7750. (Also, see the "Related Documentation" section.)
Networks with Cisco 2600 and Cisco 3600 Series Routers
In a network environment that uses Cisco 2600 series routers, Cisco 3600 series routers, and Cisco ICS 7750s, to avoid intermittent call setup failures all platforms should run Cisco IOS Release 12.2(2)XK or later.
Software Images on MRP and ASI Cards
All of the MRP and ASI cards in a Cisco ICS 7750 must run the same Cisco IOS image.
Caveats
Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
All caveats in Release 12.2 T are also in Release 12.2(2)XK. For information on caveats in Cisco IOS Release 12.2 T, refer to the Caveats for Cisco IOS Release 12.2 T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats, and are located on CCO and the Documentation CD-ROM.
Note
Resolved Caveats
The caveats listed in this section are resolved in Cisco IOS Release 12.2(2)XK.
•
•
A typical topology with this problem is an analog telephone connected to the PSTN by way of an FXO port on the same ASI81 card. (CSCdu41511)

•
Open Caveats
This section describes open caveats in Release 12.2(2)XK.
•
There is no workaround.
•
There is no workaround.
•
Workaround—Disabling VAD can solve this problem, however, if you disable VAD on a network that exhibits a significant amount of jitter (for example, greater than 100 milliseconds per second), latency becomes noticeable to the user in the form of delay and packet loss. Also, if the codec clocks are out of sync among the devices participating in the call, latency increases for the duration of the call. For example, if the codec clock at the transmitting end is 100 parts per million faster than the codec clock at the receiving end, latency increases to one-half second over the course of a one hour long connection (at 8 kHz).
•
There is no workaround.
