New Hardware and Software Features in Release 12.1(5)T7
The following sections list the new hardware and software features supported by the Cisco ICS 7750 for Release 12.1(5)T7.
Cisco ICS 7750
The Cisco Integrated Communications System (ICS) 7750 is an IP telephony system that provides managed Web-based communications applications for transforming branch-office and mid-sized business environments into Internet e-businesses. The system is built on the open and scalable Cisco AVVID (Architecture for Voice, Video and Integrated Data).
The Cisco ICS 7750 integrates the functionality of the following voice and data network components:
•
•
•
•
The Cisco ICS 7750 incorporates all of the following elements needed to deliver converged data, voice and video:
•
•
•
•
•
The Cisco ICS 7750 is a six-slot system, which houses any combination of Cisco IOS-based MRPs and/or SPEs. Various combinations of MRP and SPE cards allow a network administrator to customize the configuration to meet voice and data processing needs, such as telephony, in one integrated system. The SAP card provides fault management and events-driven alarms through electronic mail or paging and the SSP card provides Ethernet switching.
The MRP supports both digital and analog voice-trunk gateways and WAN interfaces. The MRP enables businesses to use virtual private network (VPN), firewall, IP Security (IPSec), and QoS for voice and data transmission. The Cisco ICS 7750 system uses the MRP to link to the Public Switched Telephone Network (PSTN) and existing private branch exchanges (PBXs), as well as other common analog devices, such as fax machines and teleconferencing stations. Each MRP card has two slots that accept existing Cisco Voice interface cards (VICs) and WAN interface cards (WICs). Refer to Table 5 for a complete list.
The SPE is a single-board computer that can run Cisco CallManager for intelligent call processing.
A Cisco ICS 7750 network includes peripheral hardware components, such as the following:

Note
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 12.1(5)T7 or later.
Software Images on MRP Cards
All of the MRP 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.
This section is organized as follows:
All caveats in Release 12.1(5)T are also in Release 12.1(5)T2. For information on caveats in Cisco IOS Release 12.1(5)T, refer to the Caveats for Cisco IOS Release 12.1T document. For information on caveats in Cisco IOS Release 12.1, refer to the Caveats for Cisco IOS Release 12.1 document. These publications list severity 1 and 2 caveats, and are located on Cisco.com and the Documentation CD-ROM.
Note
Resolved Caveats
This section describes resolved caveats in Release 12.1(5)T7:
•
Open Caveats
This section describes open caveats in Release 12.1(5)T7.
•
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).
•
Workaround—Limit the echo-coverage setting to 16 milliseconds in the voice-port configuration. For example, enter the command echo {coverage} 16ms voice-port.
•
There is no workaround.
•
Workaround—Disable fax relay so that the fax call makes use of the established voice path. Do this by adding the following configuration to the routers on both sides of the VoIP call leg:
router(config)# dial-peer voice tag voiprouter(config-dial-peer)# fax rate disablerouter(config-dial-peer)# no vadwhere tag is the dial peer tag you assign.
•
If this is the case, entering the show ip route EXEC command generates output similar to the following:
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masksC 10.0.0.0/8 is directly connected, FastEthernet0/0C 10.34.207.0/25 is directly connected, FastEthernet0/0S* 0.0.0.0/0 [1/0] via 10.34.207.1In the show ip route command output shown above, being in the subnet 10.0.0.0/8 prevents the MRP from pinging Cisco IP Phones with addresses such as 10.34.207.140 (which are in a different network).
Workaround—Enter the clear ip route EXEC command.
After you enter the clear ip route EXEC command, if you enter the show ip route EXEC command again, you should see output similar to the following:
10.0.0.0/25 is subnetted, 1 subnetsC 10.34.207.0 is directly connected, FastEthernet0/0S* 0.0.0.0/0 [1/0] via 10.34.207.1Related Documentation
The following sections describe the documentation available for the Cisco ICS 7750. Typically, these documents consist of hardware and software installation guides, Cisco IOS configuration and command references, system error messages, feature modules, and other documents.
Documentation is available as printed manuals or electronic documents, except for feature modules, which are available online on Cisco.com and the Documentation CD-ROM.
