  • Document No. BTSNWSS Ver. 5 (05/20/2004) Release 4.1 NETWORK SITE SURVEY NETWORK SITE SURVEY FOR SOFTWARE INSTALLATION CISCO BTS 10200 SOFTSWITCHCompany Name:       By (Name):       Date:       .Additional Data (Optional):       .PURPOSEThis Network Site Survey (NSS) is used to collect the information required byCisco BTS 10200 Softswitch application software to communicate with the service providernetwork. The information you provide in this NSS will be used by Cisco to create a customizedNetwork Information Data Sheet (NIDS) for your system. The NIDS contains the data used duringinstallation of the application software. Cisco will provide a copy of the NIDS to you, andrecommends that you retain it in a secure location for future reference.CAUTIONThis document should be filled out by the system administrator, or with the direct assistance of thesystem administrator. Entering incorrect data could affect traffic. Do not continue until you have thesystem administrator’s direct support.The Cisco BTS 10200 Softswitch relies on Internet Router Discovery Protocol (IRDP) for dynamicupdating of routing table. Therefore the service provider network is assumed to be IRDP capable. Ifthis is not the case, contact Cisco TAC for a review of configuration options.If you have any questions, contact Cisco TAC for assistance.PROCEDUREPages 2 through 6 are used by the service provider to specify network information. TheCisco BTS 10200 Softswitch relies on this information to identify the host platforms and to accessdomain names in the DNS.SAMPLE DATAPages 7 through 11 show a sample of a completed NSS.NETWORK DIAGRAMThe figures on pages 12 and 13 show a typical internal network and an example of networkredundancy.

  • Document No. BTSNWSS Ver. 5 (05/20/2004) Release 4.1 NETWORK SITE SURVEY NETWORK SITE SURVEY FOR SOFTWARE INSTALLATION CISCO BTS 10200 SOFTSWITCH Company Name:       By (Name):       Date:       . Note: Throughout this document, the following names are used for hosts and processes running on the Cisco BTS 10200 Softswitch: • EMS/BDMS—The Element Management System (EMS) and Bulk Data Management System (BDMS) are separate processes with the same (shared) logical address, running on the same physical host. • CA/FS—The Call Agent (CA), POTS/Tandem/Centrex Feature Server (FSPTC), and AIN Feature Server (FSAIN) are separate processes with separate logical addresses, running on the same physical host. GENERAL NETWORK CONFIGURATION DATA Parameter Value Comments Site ID Assign a unique CORBA site identifier to this Cisco BTS 10200 Softswitch. The allowed identifier length is 3 to 12 ASCII characters, for example: dallas01 NTP Timehost(s) Enter the IP address of the timehost(s) that all EMS/BDMS and CA/FS hosts use to sync their time. Subnet Mask for Subnetmask is required for both external network 1 and 2. external network 1 Example: 255.255.255.0 Subnet Mask for external network 2 Primary DNS: Primary DNS is required. Hostname and IP The Primary DNS must be on a network reachable by all the Address hosts comprising the Cisco BTS 10200 Softswitch. (See drawings on pages 12 and 13.) Note: DNS=Domain Name Server Secondary DNS: Secondary DNS is strongly recommended. Hostname and IP The secondary DNS must also be on a network reachable by all the Address hosts comprising the Cisco BTS 10200 Softswitch. In order to assure reachability in the face of potential network outages, it is strongly recommended that the secondary DNS be reachable via a separate network with paths diverse from the primary DNS. (See drawings on pages 14 and 15.) CAUTION: If the DNS servers are both reachable via a single network path, and that path fails, then a traffic interruption will occur. NSCD and NAMED A value of yes means that both NSCD and NAMED functionality for DNS processes are enabled in the network and are available to lookup the Cisco BTS 10200. A value of n means that both processes are not available to the Cisco BTS 10200. NSCD = Name Service Cache Daemon NAMED = Domain Name ServerAlarm Panel: Enter the hostname and IP address of the Alarm PanelHostname and IP which provides console access to theAddress.

  • Document No. BTSNWSS Ver. 5 (05/20/2004) Release 4.1 NETWORK SITE SURVEY HOSTNAMES AND DOMAIN NAMESNotes: • Maximum of 10 ASCII characters for each hostname. • Maximum of 46 ASCII characters for the domain name. • “x” is the IP octet you select for each component; use four unique values of “x” for the four components. “x” must be a number 0 to 255. In a Class C network, “x” designates the 4th octet in an IP address (i.e., 192.150.50.x). Component Information: Component Domain Name IP Octet “x” Hostname Enter one domain name For Component Side A EMS/BDMS Side B EMS/BDMS Side A CA/FS Side B CA/FS CA and FS INSTANCESEach component type—CA, POTS/Tandem/Centrex FS, and AIN FS—requires a fixed designation known asan instance. The Side A and Side B components of the same type share the same instance. For example,the instance for the Side A and Side B CA could be CA146, and the instance for the FS could be FSPTC235and FSAIN205. These instances are used when provisioning the Cisco BTS 10200 Softswitch, so that thecomponents can communicate with each other. The prefix part of the instance is preset as CA, FSPTC, EM,BDMS or FSAIN. Currently, EM and BDMS instances numbers are fixed as 01 and cannot be changed. Thenumeric portion can be any number between 100 and 999. The instance numbers must be unique for CA,FSPTC, and FSAIN.When expanding the Cisco BTS 10200 Softswitch by addition of CAs or FSs, it is necessary for the new CAor FS to be given an instance different from any instance already present in the Cisco BTS 10200 Softswitch.To facilitate identification of network messages, it is also necessary to use different instance numbers forevery Cisco BTS 10200 Softswitch component in the service provider network.Please fill in the instance for each component type if left blank the default values will be used: Component Type Default Instance CA 146 FSPTC 235 FSAIN 205© 2004 Cisco Systems, Inc.—All Rights Reserved Cisco Confidential Page 3 of 14 View slide
