17 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 21 RSSI Recommended Values.. -69dBm or better RSSI means good reception and better through. -70 to -89dBm is considered to be ok with reasonable throughput. -89 to -99 dBm is bad reception and throughput will vary significantly. -99 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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.

26 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 HWIC in a Router PC with Sierra SWFlash Special USB to RJ45 cable

27 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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.

31 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 32 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 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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?

59 Common Field Issues Common field issues include: network attach failure PDP activation failure Loss of connectivity Modem initialization sequence: modem initiates a network scan modem attaches to a network automatically once a network is found user can establish a Data Session (activate PDP context) after the attach procedure completes Cisco Systems Inc

60 Troubleshoot Network Attach Issues Symptom: show cellular network shows the modem is not attached to the cellular network Sample show cellular 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 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 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 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) = 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 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 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 security sample output if SIM is missing or not properly inserted Router#show cellular 0/0/0 security Card Holder Verification (CHV1) = Disabled SIM Status = Removed SIM User Operation Required = None Number of CHV1 Retries remaining = 255 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 hardware output 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 profiles Note that 1. Username and password have to configured in GSM profile on HSPA-U and HSPA+7 EHWICs and fixed platform SKUs using “cellular gsm profile create” command. 2. 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 network” output contact the carrier to verify account provisioning Cisco Systems Inc

64 Troubleshoot PDP Activation Issues (Cont’ed) Check if chat-script has been configured properly Cisco Systems Inc ModemSample 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

65 Troubleshoot PDP Activation Issues (Cont’ed) Check if cellular interface and/or dialer interface are configured properly Cisco Systems Inc Note that dialer list, ip route must be configured correctly. PPP or SLIP Configuration non-HSPA+7 modems encapsulation ppp ppp chap hostname ppp chap password ppp ipcp dns request HSPA+7 modem encapsulation slip Dialer Configuration async mode interactive dialer in-band dialer string dialer-group 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

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 rssi history Check tx/rx packet counts Verify if packet counts shown in show interface cellular can be related to byte packets in “show cellular connection” Cisco Systems Inc

67 Use EEM Script as A Workaround Event IPSLA object state MIB objects Cisco Systems Inc Action Clear line or shut/no shut cellular interface – terminate the data call Reset or power-cycle the modem Sample Configuration: ip sla 21 icmp-echo source-interface Vlan2 frequency 360 timeout 6000 ip sla schedule 21 life forever start-time now action 560 if $_remainder eq 0 action 570 syslog msg "Modem Power Cycle. Wait 2 min..." action 580 cli command "enable" action 590 cli command "config t" action 600 cli command "service internal" action 610 cli command "end" action 620 wait 1 action 630 cli command "test $cell_mod modem-power-cycle“ action 640 else …

68 Use EEM Script as A Workaround (cont’ed) Cisco Systems Inc 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 Complete sample script can be downloaded from - 43&softwareid= &release=TEST.1.0&relind=AVAILABLE&rellifecycle=& reltype=latest

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

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