This object models cellular interfaces and access points. Enables or disables roaming. Current roaming status. {{numentries}} Cellular interface table (a stackable interface object as described in {{bibref|TR-181i2|Section 4.2}}). Each instance of this object models a cellular modem with a single radio and can reference multiple {{object|.TrustedElements.SIM.}}. Corresponds to {{enum|GPRS|CurrentAccessTechnology}}, {{enum|UMTS|CurrentAccessTechnology}}, {{enum|LTE|CurrentAccessTechnology}} etc ''ATTACHED'' status Corresponds to {{enum|GPRS|CurrentAccessTechnology}}, {{enum|UMTS|CurrentAccessTechnology}}, {{enum|LTE|CurrentAccessTechnology}} etc ''DETACHED'' status International Mobile Station Equipment Identity number, represented as a 15 digit string (digits 0-9). Access technologies supported by the interface. GSM with GPRS GSM with EDGE UMTS with High Speed Packet Access (HSPA {{bibref|3GPP-HSPA}}) 5G New Radio Preferred access technology. Access technology that is currently in use. List of available networks. Name of the network which will be used, or {{empty}} if the network is selected automatically. The value is {{empty}} if no network is found, or if the network specified in {{param|NetworkRequested}} is not found. The received signal strength in {{units}}. The allowed values depend on {{param|CurrentAccessTechnology}}: * For {{enum|GPRS|SupportedAccessTechnologies}}, {{enum|EDGE|SupportedAccessTechnologies}} the range is -111 {{units}} to -49 {{units}} * For {{enum|UMTS|SupportedAccessTechnologies}}, {{enum|UMTSHSPA|SupportedAccessTechnologies}} the range is -117 {{units}} to -54 {{units}} * For {{enum|LTE|SupportedAccessTechnologies}}, {{enum|NR|SupportedAccessTechnologies}} the range is -117 {{units}} to -25 {{units}} Note: An undetectable signal is indicated by the appropriate lower limit, e.g. -117 {{units}} for LTE. The Reference Signal Received Power in {{units}} for {{enum|LTE|SupportedAccessTechnologies}}, {{enum|NR|SupportedAccessTechnologies}} values of {{param|CurrentAccessTechnology}}: * The valid range of RSRP values from worst to best is -140 {{units}} to -44 {{units}} * Set to {{maxval}} if RSRP is not supported by the current access technology The Reference Signal Received Quality in {{units}} for {{enum|LTE|SupportedAccessTechnologies}}, {{enum|NR|SupportedAccessTechnologies}} values of {{param|CurrentAccessTechnology}}: * RSRQ is calculated using RSSI and RSRP values using RSRQ = (N*RSRP)/RSSI where N is the number of resource blocks (bandwidth). * The valid range of RSRQ values from worst to best is -20 {{units}} to -3 {{units}}. * Set to {{maxval}} if RSRQ is not supported by the current access technology. The current maximum attainable data rate upstream (expressed in {{units}}). The current maximum attainable data rate downstream (expressed in {{units}}). Each list item references a SIM with which the interface is associated. USIM (Universal Subscriber Identity Module or SIM card) parameters for the interface. {{deprecated|2.19|because moved to {{object|.TrustedElements.SIM}}}} The current status of the USIM card. No card available Card is available but not verified Card can be used; either valid PIN was entered, or PIN check is deactivated USIM is blocked because the maximum number of invalid PIN entries was exceeded An error was detected with the card International Mobile Subscriber Identity represented as a string with either 14 or 15 digits (digits 0-9). The first 3 digits are the mobile country code (MCC), which are followed by the mobile network code (MNC), either 2 digits (European standard) or 3 digits (North American standard), followed by the mobile subscription identification number (MSIN). Integrated Circuit Card Identifier represented as a string of up to 20 digits (digits 0-9). The number is composed of the following parts: * Major industry identifier (MII), 2 fixed digits, 89 for telecommunication purposes. * Country code, 1–3 digits, as defined by ITU-T recommendation {{bibref|ITU-E.164}}. * identifier, 1–4 digits. * Individual account identification number. Its length is variable, but every number under one IIN will have the same length. * Single check digit calculated from the other digits using the Luhn algorithm. For cards using an ICCID according to {{bibref|ITU-E.118}} the maximum length is 19 Digits, for GSM cards 20 digits. Mobile Subscriber Integrated Service Digital Network Number, a number uniquely identifying a subscription in a GSM, UMTS, or LTE mobile network. {{bibref|ITU-E.164}} Controls the PIN verification of the USIM card. Check the PIN with each access to a new network Check the PIN with first access after (re)boot Disable the PIN check Allows the Controller to change the USIM PIN used for SIM card activation. The object models SMS (Short Message Service) features. {{numentries}} {{numentries}} Represents a SMS storage location. Each instance of this object corresponds to a distinct SMS storage area. Multiple instances of this object may exist, each representing a different storage type (e.g., SM SIM card, ME device memory). Specifies the storage location e.g. SM SIM card, ME device memory. The maximum number of SMS messages in {{object|Device.Cellular.Interface.{i}.SMS.Message}} that can be stored in Storage. Indicates whether the SMS Storage is available to receive new messages. {{true}} means that there is storage still available; {{false}} means that the storage is full. The number of SMS messages in {{object|Device.Cellular.Interface.{i}.SMS.Message}} that the Storage entity has room to store, which can not exceed {{param|Capacity}}. This object models incoming SMS configuration. Specifies the memory path where the messages are stored. Maximum number of incoming SMS messages to be stored. If the number of incoming messages in {{object|Device.Cellular.Interface.{i}.SMS.Message}} exceeds CapacityLimit, the oldest incoming messages will be removed automatically to prevent storage overfilling. -1 disables automatic messages removal. This object models outgoing SMS configuration. Specifies the memory path where the messages are stored. Maximum number of outgoing SMS messages to be stored. If the number of outgoing messages in {{object|Device.Cellular.Interface.{i}.SMS.Message}} exceeds CapacityLimit, the oldest outgoing messages will be removed automatically to prevent storage overfilling. -1 disables automatic messages removal. This object models individual SMS messages, including both received and sent entries. Phone number of the SMS sender. Phone number of the SMS receiver. Indicates the time an incoming SMS was received (when {{param|Status}} is {{enum|Received|Status}}) or when an outgoing SMS was sent (when {{param|Status}} is {{enum|Sent|Status}}). Text of the SMS message. Specifies the memory path where the messages are stored. Indicates the status of the message. The incoming message has been received, stored successfully, and has been marked as read. The incoming message has been received and stored successfully. The outgoing message has been stored and sent successfully. The outgoing message has been created, but has not been sent yet. Message status processing error. Indicates the type of the message. SMS message with a single receiver. SMS message with multiple receivers. Receipt of a SMS message. Cellular Access Point table. Each entry is identified by an {{param|APN}} (Access Point Name) that identifies a gateway between the mobile network and another computer network. Note: Device 2.19 grouped the APN and Interface keys into one combined key. Enables or disables the Access Point. Access Point Name. Username used to authenticate the CPE when making a connection to the Access Point. Password used to authenticate the CPE when making a connection to the Access Point. Proxy server IP address. Proxy server port. Reference to the interface with which the access point is associated. This parameter specifies the type of APN being used. Common values are "default", "mms", "ims", "hipri", ... The specific values supported may vary depending on the network operator. If the APN type is not applicable, this parameter may be {{empty}}.
