17 Need for Carrier provisioning
CDMA technology does not use SIM card for carrier/subscriber provisioning, so this information has to be provisioned on the modem The carrier specific configuration on the 3G modem are: Modem ESN and Security Keys Carrier PRI and PRL Modem Firmware Additionally a security information file (flat file) generated during modem provisioning that’s needs to be sent back to the carrier To support a new CDMA carrier, there are 2 options: Create additional CDMA HWIC SKU and perform provisioning in manufacturing Use the generic CDMA HWIC and defer provisioning to Cisco partner/reseller

18 Now, in practice Actual Bandwidth Values depends on the following Factors
RSSI Value ECIO Value Cellular Medium shared among Multiple Users. Distance between Site to BTS Tower

19 Antenna The extended out-door antenna is meant to extend the reach outside the surroundings if the surroundings (lot of metal cages etc.) blocking the radio signal. But it can not improve the already weak signal. cell-site itself is breathing heavily (in case of extreme over-sbuscription and inadequate radio resource planning), the signal will fluctuate. In that case, even the extended antennas won't help

20 What is the recommended Values of SNR and ECIO to declare site signal strength bad or fluctuating Or requires Diversity Antenna or Outdoor Antenna

21 RSSI Recommended Values
RSSI Recommended Values dBm or better RSSI means good reception and better through to -89dBm is considered to be ok with reasonable throughput to -99 dBm is bad reception and throughput will vary significantly dBm onwards, should expect loss of connectivity. if -99, will see modems are working fine : Short answer, Yes, beyond 90 - nothing guaranteed but have seen card working at -90s at times but with very low throughput and high delays.

22 ECIO Recommended Value
ECIO value as low as possible. Lab tests have indicated ECIO ≤-2 dB. If you observed a value of -7 or something similar, you might have a very noisy environment, which may in turn cause retransmissions of the packets, lower throughput, call drops, etc.

23 Generic CDMA HWIC model
Sierra Wireless creates a generic CDMA modem Sierra Wireless Sierra Wireless Cisco Manufacturing inserts the generic modem into the generic CDMA HWIC SKU Cisco Manufacturing Generic CDMA HWIC Local Partner/Disti stocks the generic CDMA HWIC and sends them to local vendor Distributor/ Partner Provisioning Partner CDMA Carrier Local vendor provisions the modem Customer/ Partner Provisioned CDMA HWIC

24 India CDMA SP Currently in India we have following THREE Major 3G CDMA Service provider , who offers different variant of activation process . 2 S.NO CDMA SP Activation Method 1 BSNL Manual (ESN Based) 2 Reliance OTAF or OTAF w/IVR (Need Flat File) 3 TATA

25 Migration between CDMA Service provider
Example: Provision With Factory Reset Package Provision w/ Reliance or TATA CDMA By Default BSNL CDMA Modem Requirements On site Required Cable of following  3G4G-CAB-USB-RSVD(=) is for the “mini-USB to regular USB” RSVD For Fixed 3G OR 3G-CAB-RJ45-RSVD(=) is for the “RJ45 to regular USB” RSVD For Module 3G. WINDOWS XP Laptop Package tools and Firmware can be downloaded from CCO

26 Modem Provisioning Process
Sierra Wireless provides a GUI based modem provisioning tool The 3G HWIC allows direct access to modem via the diag port Provisioning steps: Boot up router with 3G HWIC Enable modem access from diag port using an IOS command: test cell-hwic x/x/x usb-to-dm (Note: This requires that you have “service internal” enabled in the config mode) Connect the USB-to-RJ45 cable from the PC with SWFlash to HWIC diag port Run SWFlash on the PC which would download PRI/PRL/FW and create an entry in flat file (~10 mins) Send the combined flat file to the carrier PC with Sierra SWFlash Special USB to RJ45 cable HWIC in a Router

27 Modem Provisioning Tools/Software
SWFlash –Configuration Tool This is the Windows program that provisions the modem using a package. This program uses the CCT to program/configure modems Package - Configuration bundle of: Modem Firmware PRL – Preferred Roaming List (provided by carrier) PRI – Product Release Instructions (aka modem NV settings) Flat File Output file created by CCT. Contains modem security keys and configuration data that must be sent to the appropriate cellular carrier (copies to Sierra Wireless)

28 SWFlash Tool - PC System Requirements
Basic requirements Windows XP Professional (SP 2), WIN7 32 Bit OS computer Built-in USB or UART connectivity appropriate for modem 256MB+ memory, 1GB+ hard disk space Microsoft Excel Connection to modem on the HWIC Cisco 3G HWIC product team would provide special USB-to-RJ45 cable Network connectivity to transfer flat file Note: SWFlash software bundle would be provided by Cisco to the provisioning partner.

29 Modem Provisioning – Software Tools

30 Hands on Session Let us Continue, How to install , Configure and Provision the CDMA Packages.

31 Main Antenna vs Diversity Antenna
The diversity antenna supports only downlink; The main antenna supports both uplink and downlink . Multipath is a form of RF interference that occurs when a radio signal has more than one path between the receiver and the transmitter. This situation occurs in cells with metallic or other RF-reflective surfaces, such as furniture, walls, or coated glass. The diversity antenna ports are designed for spatial diversity, and the radio checks the other antenna only when it encounters errors. Contd..

32 Diversity antenna should be used always wherever possible
Diversity antenna should be used always wherever possible. Typically, when the signals are not good (worse than -69dBm ) and lot of interference due to surrounded by lot of radio sources, metal casings, metal cabinates, the ECIO value goes down. In such scenaro, Diversity plays an important role to improve the overall throughput. On what basis will decide to choose in door or out door or low antenna? For commercial deployments where the router is generally deep inside the buildings (in a closet or rack room), it is recommended to use external/outdoor antenna so the antenna can be placed out side the room/closet and can receive the unattenuated cellular signal. Recommended deployment for antenna is at the edge of the building (glass-wall or window etc.) or on the roof-top of the building for better reception.

33 Site Survey Checklist What is distance between Site to BTS Tower?. Volume of Subscribes over that region? What type of CDMA service offering by Service Provider? What is the RSSI (Signal Value) at the Place, where we kept router?. What is the RSSI Signal value at Outside?

34 CDMA Activation Methods
Manual Activation OTAF Activation OTAF Activation using IVR During OTAF activation process, IVR system expect to receive DTMF digits for various selection process. Using Cisco EEM scripts, we can send the DTMF digits during OTAF process.

Symptom: show cellular <unit> network shows the modem is not attached to the cellular network Sample show cellular <unit> network output when the modem is attached to network Current Service Status = Normal, Service Error = None Current Service = Combined Packet Service = HSPA (Attached) Packet Session Status = Active Current Roaming Status = Home Network Selection Mode = Automatic Country = USA, Network = AT&T Mobile Country Code (MCC) = 310 Mobile Network Code (MNC) = 410 Sample show cellular <unit> network output when the modem is NOT attached to network Current Service Status = Emergency Only, Service Error = None Current Service = Invalid Packet Service = None Packet Session Status = Inactive 2012 Cisco Systems Inc

61 Troubleshoot Network Attach Issues (cont’ed)
Solution/Steps: Check antenna connection make sure antenna is firmly attached Check network coverage check RSSI value in show cellular <unit> radio [history …] adjust antenna location if necessary Check modem is in online state modem must be in “Online” mode in order to attach to the network. The radio is turned off and not transmitting if it is in “Low Power Mode” Router#show cellular 0/0/0 hard Modem Firmware Version = T1_0_3_2AP R361 CNS Modem Firmware built = 04/15/11 Hardware Version = 1.0 International Mobile Subscriber Identity (IMSI) = 00000 International Mobile Equipment Identity (IMEI) = Integrated Circuit Card ID (ICCID) = Mobile Subscriber International Subscriber IDentity Number (MSISDN) = Factory Serial Number (FSN) = CC Modem Status = Online 2012 Cisco Systems Inc

62 Troubleshoot Network Attach Issues (cont’ed)
Check SIM presence status and SIM lock status verify a SIM is properly inserted and the PIN is enabled show cellular <unit> security sample output if SIM is installed properly Router#show cellular 0/0/0 security Card Holder Verification (CHV1) = Disabled SIM Status = OK SIM User Operation Required = None Number of CHV1 Retries remaining = 255 show cellular <unit> security sample output if SIM is missing or not properly inserted SIM Status = Removed Note that SIM presence status is also displayed in show controller cellular 0 on fixed platforms with dual SIM support Router#show controller cellular 0 ... Cellular Dual SIM details: No SIM present Check if a valid SIM is inserted, IMSI verify IMSI number in show cellular <unit> hardware output 2012 Cisco Systems Inc

63 Troubleshoot PDP Activation Issues
Symptom: cellular service has been acquired, but ping fails. Solution/steps: Check if GSM or data profile is configured properly verify APN, username, and password settings in show cellular <unit> profiles Note that Username and password have to configured in GSM profile on HSPA-U and HSPA+7 EHWICs and fixed platform SKUs using “cellular <unit> gsm profile create” command. Username and password are limited to 32 characters in pre-15.1(4)M4 releases. Check if there is any subscription issue check “Service Error” in “show cellular <unit> network” output contact the carrier to verify account provisioning 2012 Cisco Systems Inc

64 Troubleshoot PDP Activation Issues (Cont’ed)
Check if chat-script has been configured properly Modem Sample chat script CDMA chat-script cdma "" "ATDT#777" TIMEOUT 30 "CONNECT" GSM/HSPA chat-script umts "" "atdt*99#" TIMEOUT 180 "CONNECT" HSPA+ chat-script plus "" "at!scact=1,1" TIMEOUT 60 "OK" Check if line has been configured correctly. Sample configuration: line 3 script dialer plus modem InOut no exec transport input all 2012 Cisco Systems Inc

65 Troubleshoot PDP Activation Issues (Cont’ed)
Check if cellular interface and/or dialer interface are configured properly PPP or SLIP Configuration non-HSPA+7 modems encapsulation ppp ppp chap hostname <username> ppp chap password <passwd> ppp ipcp dns request HSPA+7 modem encapsulation slip Dialer Configuration async mode interactive dialer in-band dialer string <string> dialer-group <number> IP Address configuration ip address negotiated Sample Configuration: interface Cellular0/0/0 ip address negotiated ip nat outside encapsulation ppp dialer in-band dialer string gsm dialer-group 1 async mode interactive ppp ipcp dns request Note that dialer list, ip route must be configured correctly. 2012 Cisco Systems Inc

66 Troubleshoot Loss of Connectivity Issues
Symptom: data traffic passes through initially but stops after sometime. Solution/steps: check PDP session status and IP address Verify if PDP session is still active and if IP address is available Check RSSI value Verify if signal level fluctuates in show cellular <unit> rssi history Check tx/rx packet counts Verify if packet counts shown in show interface cellular <unit> can be related to byte packets in “show cellular <unit> connection” 2012 Cisco Systems Inc

67 Use EEM Script as A Workaround
Sample Configuration: ip sla 21 icmp-echo source-interface Vlan2 frequency 360 timeout 6000 ip sla schedule 21 life forever start-time now Event IPSLA object state MIB objects Action Clear line or shut/no shut cellular interface – terminate the data call Reset or power-cycle the modem action if $_remainder eq 0 action syslog msg "Modem Power Cycle. Wait 2 min..." action cli command "enable" action cli command "config t" action cli command "service internal" action cli command "end" action wait 1 action cli command "test $cell_mod modem-power-cycle“ action else 2012 Cisco Systems Inc

68 Use EEM Script as A Workaround (cont’ed)
Complete sample script can be downloaded from - Please make sure to suspend EEM script using “event manager scheduler Suspend” when you control the modem from CLI. This is to avoid contention between EEM script and CLI 2012 Cisco Systems Inc

69 Problem in making a GSM Data Call
No Call initiate No Successful SIM card inserted? Insert a valid SIM card Yes Yes done No No Service Available/Attached? GSM profile configured? Create Profile Yes Yes Check antenna & RSSI level Check configuration chat script dialer list line <line#> interface cellular <unit> ip route 2012 Cisco Systems Inc

70 Problem in Making A CDMA Data Call
Successful No Call initiate No modem activated? activate modem Yes done Yes No Service Available? Check antenna & RSSI level Yes Check configuration chat script dialer list line <line#> interface cellular <unit> ip route 2012 Cisco Systems Inc
