Note Release 4.1 (or later) supports only the SIGTRAN ITP configuration for the SS7 interface. Previous versions of the Cisco BTS 10200 Softswitch used Ulticom SS7 interface cards. These Ulticom SS7 interface cards can be decommissioned in place; they do not have to be removed from the Call Agent.
•Power distribution unit (PDU) for both AC and DC systems.
–DC-powered systems require two (redundant) feeds of 40A at -48 VDC.
–AC-powered systems require two (redundant) circuits of 20A at 120 VAC.
Note Both AC and DC systems require two redundant feeds. Cisco highly recommends that uninterruptable power supplies be provided for both AC and DC systems.
•Alarm Panel that includes a terminal server.
Note You can order just the Cisco BTS 10200 Softswitch software for use in a Cisco Systems solution where you supply the Cisco-specified hardware. The Cisco TAC will only support Cisco software running on Cisco-approved hardware configurations. The software is not supported on any other hardware.
Sun Microsystems hardware can be ordered directly from the vendor or a Sun Value Added Reseller; however, Cisco TAC does not support hardware when purchased directly from Sun or another vendor. Hardware support contracts should be purchased from Sun, or the Sun Value Added Reseller.
Hardware available from Cisco Systems Inc. for North American customers is listed below as the CCPU configuration. Determine if you need AC or DC, and if you want the hardware in a cabinet or ready to mount in a customer rack. Work with a Cisco BTS 10200 product manager to determine the appropriate load for your customer. This base software includes 1,000 subscriber/DS0 licenses and 5 CPS. You will need to order RTU and CPS licenses as appropriate if additional subscribers are needed.
The Cisco BTS 10200 Softswitch is available only in duplex (continuous-service) configurations.
Table 1 lists the hardware requirements for the Cisco BTS 10200 Softswitch Call Agent (CA) and Feature Server (FS) platform.
Caution Before choosing a hardware configuration, consult with your Cisco representative to determine the hardware that will give you the best results based on your network configuration, proposed traffic, and desired call processing power. In particular, called-number analysis or screening, long call hold times, and service control point (SCP) queries might require additional resources.

Cisco ITP Signaling Gateways
The Cisco IP Transfer Point (ITP) is a comprehensive product for transporting Signaling System 7 (SS7) traffic over traditional time-division multiplexing (TDM) networks or advanced SS7-over-IP (SS7oIP) networks. Cisco ITP Signaling Gateways are required to provide SS7 interconnectivity for the Cisco BTS 10200 Softswitch in Release 4.1. If using SS7, you must purchase ITP equipment as described here.
The Cisco IP Transfer Point is implemented on the Cisco 2600XM Series Router (2650XM & 2651XM), the Cisco 7200 Series Router (7204VXR, 7206VXR), the Cisco 7301 Router and the Cisco 7500 Series Router (7507, 7513). All hardware models function similarly by performing MTP3 and SCCP routing over SS7 TDM links or over an IP (or dual IP) network.
The Cisco ITP 2651, 7301, and 7507 Signaling Gateways are carrier class routers with a transparent SS7oIP convergence solution. The 26xx offers 2 or 4 SS7 links, the 73xx supports up to 80 SS7 links, while the 7507 provides from 32 to 256+ SS7 links.
The following three tables list the part numbers and quantities of boxes necessary for the Cisco ITP configurations that support the Cisco BTS 10200 Softswitch in Release 4.1. For more information see the Cisco ITP Product Data Sheet.

The Cisco BTS 10200 Softswitch Release 4.1 (900-04.01.00.Vxx) software is required to run the Cisco BTS 10200 Softswitch on the hardware platforms listed above.
Note Network Time Protocol (NTP) software is installed with Sun Solaris. Be sure to configure your Cisco BTS 10200 Softswitch to use NTP or the equivalent time synchronization software. For information on how to reconfigure the NTP, refer to the Release 4.1 installation procedure.
In the pre-3.5.3 releases, each Call Agent (CA) and EMS was configured to individually synchronize up to a specified NTP server. In later releases, configuring NTP changes with the new XNTP package. NTP is now configured so that the EMSs synchronize directly to the NTP server and the Call Agent's synchronize to the EMS.
Caution Users should never attempt to modify the system date or time in their Cisco BTS 10200 Softswitch host machines while system components (CA, FS, EMS, and BDMS) are running. This could cause the system to have serious problems. Allow the Solaris OS to obtain the time automatically through NTP services.
The following optional software can also be used with Cisco BTS 10200 Softswitch Release 4.1.
Cisco Extensible Provisioning Object Manager
You can use the Cisco Extensible Provisioning Object Manager (EPOM) Release 2.1 software as a provisioning tool for Cisco BTS 10200 Softswitch Release 4.1.
Note The Cisco BTS 10200 Softswitch Release 4.1 software uses OpenORB as the CORBA interface. When using EPOM with this release, you must upgrade to EPOM Release 2.1.
Cisco Self-Service Phone Administration
You can use the Cisco Self-Service Phone Administration (SPA), Version 1.0, which allows phones to be organized into accounts and managed by end users to manipulate existing features and query account information without service provider intervention. This reduces service provider costs while enhancing the user's product experience. When the service provider has installed Cisco SPA and configured it using the Cisco SPA operation and configuration tool, all that remains is creating accounts for users to manage using their own phones. The Cisco SPA application and the Cisco SPA operation and configuration tool are described in the Cisco SPA Installation and Users Guide.
Software Only Purchase
When ordering the software-only solution, you will work with the Cisco BTS 10200 Softswitch product manager to determine the correct software load. The base software load includes licenses for 1,000 subscribers/DS0 licenses and 5 CPS. If you need additional RTU and CPS, you'll need to order multiple RTU (in increments of 1K subs) and CPS licenses as appropriate.
Note Sun hardware can be ordered directly from the vendor or a Sun Value Added Reseller; however, the Cisco TAC does not support hardware when purchased directly from Sun or another vendor. Hardware support contracts should be purchased from Sun or the Sun Value Added Reseller when purchasing directly.
Table 8 lists the specific peripheral platforms, functions, and software loads that have been tested by Cisco for interoperability with the Cisco BTS 10200 Softswitch Release 4.1 software. Earlier or later releases of platform software might be interoperable and it might be possible to use other functions on these platforms. This list certifies only that the required interoperation of these platforms, the functions listed, and the protocols listed has been successfully tested with the Cisco BTS 10200 Softswitch.

Operator access to the Cisco BTS 10200 Softswitch is available only by secure shell (SSH) session to the EMS over Ethernet. Communications can be interactive or batch mode using secure FTP (SFTP). With release 4.1, you must have secure FTP (SFTP) capabilities.
For detailed installation procedures for the Release 4.1 software, refer to the Cisco BTS 10200 Softswitch Application Installation Guide.
New and Changed Information
With Release 4.1, Cisco BTS 10200 Softswitch introduces new features to enhance its capabilities. This section describes the new features available in Release 4.1, which include the following:
This feature reduces the number of network interfaces on the Cisco BTS 10200 Call Agent/Feature Server and the EMS/BDMS hosts to two network interfaces per host computer.
The Cisco BTS 10200 Softswitch Release 4.1 provides SIGTRAN SS7 signaling, which allows quick turn-around on the development of new International SS7 variants, such as China ISUP, as well as SS7 support domestically.
OpenORB was added as the CORBA interface in an earlier release. Starting with Release 4.1, OpenORB replaces Inprise Visibroker as the CORBA interface for the Cisco BTS 10200.
The Cisco BTS 10200 Softswitch Release 4.1 can generate either traditional Call Data Block (CDB) or PacketCable Event Message (EM) billing data, but not both simultaneously.
New PacketCable-based features and functions have been introduced in the Cisco BTS 10200 Release 4.1 software.
The UDP-based Annex E feature of ITU-T Recommendation H.323 is now supported by the Cisco BTS 10200 Softswitch Release 4.1.
IPManager is a UNIX shell script that manages a set of logical interfaces to provide another layer of redundancy.
The CIC audit feature enables the Cisco BTS 10200 Softswitch to recognize when an SS7 trunk is in the hung state and to restore the trunk to a usable state.
Cisco BTS 10200 Softswitch processes might exit due to an internal error or termination by the platform. This new feature enables restart of the processes that shut down, preserving stable calls.
Release 4.1 supports many SIP devices and endpoints.
Several new commands are supported in Release 4.1.
This section provides a listing of, and links to, all of the Release 4.1 user documentation.
Reduced Physical Interfaces
The Reduced Physical Interfaces feature reduces the number of network interfaces on the Call Agent/Feature Server and the EMS/BDMS hosts to two network interfaces per host computer. The reduction allows the Cisco BTS 10200 to run on smaller, or less expensive, host computers, since the number of required router ports is reduced. In addition, it creates redundant local area networks (LANs) for the management of the Cisco BTS 10200 Softswitch.
For more information, refer to the Cisco BTS 10200 Softswitch Reduced Physical Interfaces Feature Module.
Currently, routing on Cisco gateways is based on generic parameters such as originating number, destination number, and port source. Adding support for SS7 ISUP messages allows the VoIP network to use additional routing enhancements found in traditional TDM switches.
Cisco BTS 10200 Release 4.1 implements SIGTRAN-based SS7 signaling and includes the following embedded SS7 ISUP variants:
•SS7 ANSI ISUP
•SS7 ITU ISUP
•SS7 China ISUP
•SS7 Mexico ISUP
SIGTRAN-Based SS7 ANSI Signaling
Release 4.1 introduces SIGTRAN-based ANSI support in the an SS7 ANSI implementation
The Cisco BTS 10200 Softswitch SS7 ANSI ISUP feature implements North America ISUP through a signaling transportation (SIGTRAN)-based ANSI signaling gateway, providing the ability to port SIGTRAN (SCTP/M3UA) and the upper SS7 layers (ISUP, SCCP, TCAP, AIN) to an IP network.
For more information, see the Cisco BTS 10200 Softswitch SS7 ANSI Implementation Feature Module and the Cisco BTS 10200 Softswitch SS7 ANSI ISUP Implementation Feature Module.
SS7 ANSI ISUP also implements new traffic statistic measurements for these signaling protocols:
Refer to the Cisco BTS 10200 Softswitch Release 4.1 Operations, Maintenance, and Troubleshooting Manual. for more information about all existing Cisco BTS 10200 Softswitch traffic measurements.
China SS7 ISUP
The International Telecommunications Union (ITU) Signaling System 7 (SS7) Integrated Services Digital Network (ISDN) User Part (ISUP) feature implements China ISUP via SIGTRAN to a SIGTRAN-based Signaling Gateway. The Cisco BTS 10200 Softswitch is coupled to the SS7 signaling network via an external SIGTRAN signaling gateway, one of three models of Cisco IP Termination (IPT) devices. The Cisco IPT provides an interconnection to many ISUP and MTP signaling variants.
Note For the complete list of available ISUP variants, contact the Cisco BTS 10200 product management.
The China SS7 ISUP feature allows a Cisco BTS 10200 to connect between an international SS7 network and a local voice network, supporting basic calls, caller identity, call redirection, and voice mail. The same call control and supplementary services provided over an ANSI SS7 network can also be provided over an ITU SS7 network.
China SS7 ISUP also offers support for the following features:
•China and ITU ISUP Conformance
•ITU Channel Management and Circuit Selection
•China ISUP to MGCP/H323/SIP Interworking
•China ISUP to Voice Mail (IP Unity)
•China Supplementary Services via Centrex
The Traffic Management Subsystem provides the following functions:
•Saves 48 hours of statistical data in persistent store
•Displays of summary reports
•Provides on-demand report queries
•Issues events as appropriate
For more information, refer to the Cisco BTS 10200 Softswitch China ITU SS7 Support Feature Module.
Table 9 identifies the new ISUP traffic measurements collected for China ISUP support.
For detailed information about Cisco BTS 10200 Softswitch traffic measurements provisioning and reporting, refer to the Cisco BTS 10200 Softswitch Release 4.1 Operations, Maintenance, and Troubleshooting Manual.
Mexico SS7 ISUP Support
Cisco BTS 10200 Softswitch Release 4.1 introduces the base Q.767 MDL code and the Mexico ISUP variant, based on the ITU-T Q.767 specification, Application of the ISUP for International ISDN Connections. The Mexico ISUP variant support is similar to the China SS7 ISUP variant support.
In Release 3.5.2, OpenORB was added as an option for the CORBA interface. Starting with this release, and going forward, OpenORB now replaces Inprise Visibroker as the CORBA interface. Inprise Visibroker is no longer supported for Release 4.1 or later.
OpenORB is an open source software, and supports the latest CORBA specifications (OMG CORBA 2.4.2). During installation, you can now select only OpenORB.
Note EPOM 2.1 was designed to work with OpenORB. If running previous EPOM releases such as EPOM 1.3, upgrade to EPOM 2.1 and use OpenORB.
The procedure used to install the OpenORB package is virtually unchanged from the Visibroker install package. The old CORBA Interface Servant (CIS) is removed with a package remove command in Solaris, and the "cis-install.sh" command is invoked. Once the installation is complete, all components are installed and the Name Service and CIS application are running. You can perform the process on the active EMS without switching over.
For more information on OpenORB, visit http://openorb.sourceforge.net/.
Cisco OSS Applications
The switch to OpenORB by the Cisco BTS 10200 does affect existing Cisco OSS applications that utilize the CORBA interface.
Note Cisco OSS/NMS applications include EPOM and PTC. Partner applications include CEON IPS, all of which have specific adapters for the particular ORB.
The bulk of OSS application processing involves this interface and this component of the client application should be totally unaffected. Existing customers are affected in that the client side or OSS application must use a fully compliant ORB that can interoperate with an ORB using CORBA 2.4.2 via IIOP. The original Visibroker POA was specific to the vendors' implementation of the POA.
The IDL and XML interfaces are not affected by the OpenORB migration.
Name Service Feature
You must navigate to the Cisco BTS 10200 EMS by using the Name Service feature in CORBA. At this time, each Cisco BTS 10200 creates a Name Service instance and binds the Cisco BTS 10200 objects to this local name service. Obtaining these object references for the Cisco BTS 10200 requires communication with its local Name Service.
Billing Subsystem Redesign
The billing subsystem has been redesigned in Release 4.1. Enhancements were made to Call Detail File Management, and to the CLI commands for managing the files stored on the BDMS platform at any given time. Examples of the commands include:
•report billing-file filename=%;—Displays all file names stored in /opt/bms/ftp/billing.
•report billing-file filename=xxx;—Displays the specified filename and the current state of the file.
•report billing-file state=xxx;—Displays all filenames that are in the specified state.
The following is a list of the command line tokens associated with this command and the valid values and purpose of each:
–filename—name of the billing file
–state—the current state of a given file. Valid values are:
OPEN-the file is currently being written to
PRIMARY-the file has been sent to, and acknowledged by, the billing mediation system.
SECONDARY-the file has been sent to, and acknowledged by, the billing mediation system
–start-row—The row to start displaying from in the returned result set. Range is determined by the size of the result set. (Default = 1).
–limit—The maximum number of rows to display from the result set. (Default = 50).
–display— The data columns to display from those supported by this command. The default is to display all available columns.
–order—The column by which to sort the displayed result set. Valid values are:
FILENAME—Sort by filename.
STATE—Sort by state.
•auto-refresh—Specifies if a new result set is to be created or to use the existing one if there is one available. The default value is Y.
Billing Data Generation
The Cisco BTS 10200 Softswitch Release 4.1 has the ability to provision billing support using one of the following billing data generation methods:
•Call Detail Blocks (CDBs)—This is traditional post-call billing data, which is assembled into Call Detail Records (CDRs) by an external billing mediation system or billing server.
•PacketCable event messages (EMs)—This is real-time call data flow, which is transferred to an external Record Keeping Server (RKS) that assembles CDRs from the EMs.
The Cisco BTS 10200 can be provisioned to generate either EMs or CDBs, but not both. For the detailed procedures for provisioning EM or CDB generation of billing data see the Packet Cable Feature Module.
The following PacketCable-based features and functions have been introduced in the Cisco BTS 10200 Release 4.1 software, including:
•PacketCable-based signaling security features, including implementation of IP security architecture (IPsec), key management using Internet Key Exchange (IKE), and Kerberos
•PacketCable-based media security
•Common Open Policy Service (COPS) interface measurements
•DQoS gate coordination function
In addition, the following PacketCable-based features have been updated:
•Alarms and events
•Command line interface (CLI) provisioning
Note CLI provisioning is disabled by default at Release 4.1 installation. CLI provisioning is not allowed until database licenses are applied to the Cisco BTS 10200.
H.323 Annex E Redundancy
The UDP-based Annex E feature of ITU-T Recommendation H.323 is supported by the Cisco BTS 10200. The Cisco BTS 10200 is a class-independent network switch. In addition to performing switching functions, it can also emulate up to four instances of an H.323 gateway (GW).
Annex E implementation allows for transporting H.323 signaling between the Cisco BTS 10200 and the far-end H.323 end point using UDP (connectionless) signaling instead of TCP (connection-oriented) signaling. The choice of UDP or TCP signaling is important in a Cisco BTS 10200 CA failover scenario.
If a CA failover occurs, a remote H.323 end point using TCP signaling cannot reestablish the connection with the previously-active CA, therefore clearing the stable call(s) on that connection. However, a remote H.323 end point using UDP to communicate with the Cisco BTS 10200 in a connectionless session continues to communicate with the newly-active side of the CA using the same connectionless session. This allows the remote end point to preserve and support the active call.
Using the Annex E feature is optional and configurable in the Cisco BTS 10200. Each H.323 trunk group (TG) in the Cisco BTS 10200 can be independently provisioned to support either Annex E UDP-based signaling or TCP-based signaling. Each H.323 GW instance can have multiple active outgoing TGs, with each TG independently configured for Annex E UDP or regular TCP signaling.
For more information, refer to the Cisco BTS 10200 Softswitch Annex E Support Feature Module or the "H.323 Annex E UDP Support" section of Chapter 2, "Supported Signaling Protocols," in the Cisco BTS 10200 Softswitch Release 4.1 System Description.
Cisco CallManager/H.323 Interworking
Release 4.1 enhances H.323 protocol interoperability between the Cisco BTS 10200 Softswitch, Cisco CallManager (CCM), and Cisco IOS H.323 Gateways. Interoperability of these network elements enhances the delivery of call control features between enterprise and service provider networks.
For more information, refer to the "Interoperability of Cisco BTS 10200 Softswitch with Cisco CallManager" section of Chapter 2, "Supported Signaling Protocols," in the Cisco BTS 10200 Softswitch Release 4.1 System Description.
The Cisco IP manager provides a virtual single IP address to different signaling protocol components (such as MGCP, H.323, SIP) for remote devices in oth the Primary and Secondary BTS10200 boxes. IP Manager is responsible for detecting Cisco BTS 10200 platform failover (from Primary to secondary and vise-versa) and migrating the IP address to the Current Active side.
In this release, the IP manager is an integral part of each platform (such as CallAgent and FeatureServer), and thereby provides faster response to platform failovers. Note that the IP Manager only migrates IP addresses on the same subnet. In the case of a multi-homed platform, when one of the interfaces fails, the IP Manager does not migrate the IP address to a different interface.
SS7 CIC Audits
The Cisco BTS 10200 Softswitch system may experience a "hung" SS7 trunk when an idle trunk is incorrectly perceived by the call agent to be busy. When this occurs, the call agent never selects the trunk to service new calls. This condition occurs primarily during a failover when the standby system becomes active. A call is released and the new idle call state is not replicated to the newly active call agent, who continues to perceive the trunk as busy.
The CIC audit feature enables the Cisco BTS 10200 Softswitch to recognize when an SS7 trunk is in the hung state and to restore the trunk to a usable state. A CIC audit can be performed in response to a:
•Scheduled audit request
•Long duration call
The CIC audit feature implements the following new audit types for the active call agent:
When a Cisco BTS 10200 Softswitch process exits due to an internal error (such as SIGSEGV on Unix) or is terminated by the platform, the platform restarts the processes that is exited, thereby preserving stable calls. Restarting the process is a preferred alternative to switching over to the mate.
When a process is restarted, the process audits information such as resource states, and attempts to repair inconsistencies. As compared to a switchover, process restarts preserve transient calls that are not affected by that process.
In the Cisco BTS 10200, the restartability of a process is indicated by the `Maximum restart rate' field in the platform.cfg configuration file. A zero value indicates that the process is non-restartable, while a positive value indicates that the process is restartable.
Support for SIP trunks existed in previous releases of the Cisco BTS 10200 Softswitch, but support for SIP devices is new to Release 4.1.
The SIP support feature provided in Release 4.1 was built on the existing Cisco BTS 10200 Softswitch software and hardware platform. The Cisco BTS 10200 Softswitch uses SIP and SIP for telephones (SIP-T) signaling to communicate with other SIP-based network elements. The implementation is based upon the evolving industry standards for SIP, including IETF document RFC 3261, SIP: Session Initiation Protocol. The Cisco BTS 10200 Softswitch supports both SIP trunks and SIP-based subscriber lines (SIP devices), and provides the following SIP-related functions:
•Protocol conversion between SIP and several other protocols, including SS7, PRI, ISDN, H.323, MGCP, and CAS.
•Tandem back-to-back user agent for direct SIP-to-SIP calls (trunk to trunk, phone to phone, and trunk to/from phone), and SIP-to-SIP-T calls.
•SS7 bridging between Softswitches using SIP-T methods.
For SIP feature details and applicable procedures, see the Cisco BTS 10200 Softswitch SIP Protocol Guide and the Cisco BTS 10200 Softswitch SIP Protocol Provisioning Guide.
Release 4.1 supports SIP endpoints such as SIP devices and phones, including authentication and registration management. (For example, the Cisco BTS 10200 Softswitch maintains the current location of SIP subscribers.)
To see the supported SIP endpoints, refer to the SIP Endpoints field in Table 8. For feature details and applicable procedures, see the Cisco BTS 10200 Softswitch SIP Protocol Guide and the Cisco BTS 10200 Softswitch SIP Protocol Provisioning Guide.
Several new commands are supported in Release 4.1, including:
•SNMP Trap Transmission—The retransmission of traps via SNMP is similar to "controlling" a node ins/oos/equip/etc via SNMP SETs. That is, the trap retransmission table contains the following columns: start time, end time, start sequence number, end sequence number, NMS address, and commit.
•Morning Report—Morning reports are stored in a table for 30 days (4 weeks) and can be accessed by the following command:report system_health [start-day=[MM-DD-YYYY]]; [end-day=[MM-DD-YYYY]];
•DB Connection Status and Control—These commands display the current status and allow control over the DB connection used in Oracle.
•User login discriminator—The existing user command will have new parameters added to them to allow the operator to modify the login control mechanism.
Flash Archive and Disk Mirroring
•Flash archive does not work well with Disk Suite mirroring; therefore, Cisco recommends that users create the archive without disk mirroring.
