Q. What are the default memory and memory upgrade options for Cisco 860VAE, C880W, and C880G Series ISRs?

A. Please refer to Table below for default memory and memory upgrade options for Cisco 860VAE, 880W, and 880G Series ISRs.

Q. What PoE daughter card does the C880 ISR use?

A. The C880 ISR uses a 30W 2-port PoE daughter card that is directly powered from the 12-VDC power supply of the host motherboard. It replaces the 4-port daughter card formerly used on Cisco 880 Series routers, which required a separate external -48-VDC power supply. No separate external -48-VDC power supply is required on C880 Series routers.

Q. How many PoE ports are supported on C880W Series ISRs?

A. C880W Series ISRs support 2 ports with PoE on Fast Ethernet 0 and Fast Ethernet 1. They are 802.3af-complaint, and they support 15.4W per port.

Q. Can I use the PoE daughter card from Cisco 880 Series ISRs on the C880W Series ISRs?

A. The PoE daughter card used on Cisco 880 Series routers cannot be used on C880W routers. Even though they have the same connector to the motherboard, they have different power specifications. The PoE daughter card used on Cisco 880 Series routers requires a separate external -48-VDC power supply, whereas the PoE daughter card on the C880W takes power directly from the motherboard, and no separate external power supply is required.

Q. Do the Cisco 860VAE, C880W, and C880G Series ISRs support Cisco Virtual Office?

A. Cisco Virtual Office is supported on C880W and C880G Series ISRs. The license with part number CVO800-CFG is required during the ordering process. Cisco 860VAE Series routers do not support Cisco Virtual Office at this time.

Q. Do Cisco 860VAE, C880W, and C880G Series ISRs support Cisco Wide Area Application Service Express (Cisco WAAS Express)?

A. Please refer to following Table for Cisco WAAS Express support on Cisco 860VAE, C880W, and C880G Series routers.

Q. Do Cisco 860VAE, C880W, and C880G Series ISRs support Cisco ScanSafe?

A. Cisco 860VAE, C880W, and C880G Series ISRs support the Cisco ScanSafe connector in any universal Cisco IOS Software images with security feature set (SEC) licenses. The connector securely redirects HTTP and Secure HTTP (HTTPS) traffic. There is no need for client or agent software to be installed on each laptop or desktop, so any routers anywhere in your network can act as a secure managed cloud security gateway. Cisco ScanSafe allows easy deployment with no additional hardware and can integrate into any proxy server configuration.

Q. What are the maximum-transmission-unit (MTU) sizes for different DSL interfaces on Cisco 860 and 880 Series ISRs?

A. Please refer to Table below for MTU sizes for different DSL interfaces on Cisco 860VAE and 880 Series ISRs.

Q. What new 3G plus DSL models are available in C880 Series ISRs?

A. Four new 3G plus DSL models are available: C886VAG, C887VAG, C887VAMG, and C888EG. Please refer to the data sheet “Cisco 880G Series Integrated Services Router with Embedded 3.7G” for more details.

Q. What cellular modems are integrated in the C880G Series ISRs?

A. There are two different types of carriers. One type supports third-generation Partner Project (3GPP) HSPA+, HSPA, Universal Mobile Telecommunications Service (UMTS), Enhanced Data rates for Global Evolution (EDGE), and General Packet Radio Service (GPRS), and the other supports 3GPP2 EVDO RevA/Rev0 and 1xRTT. Two cellular modems support 3GPP2: MC8705 and MC8795V, and one cellular modem supports 3GPP2: MC5728V.

Q. What is the cellular modem form factor in C880G Series ISRs?

A. The external 3G ExpressCard socket on Cisco 880G Series routers has been replaced by an internal PCIe mini-card slot on C880G Series routers. The external ExpressCard modems, therefore, have been replaced by the internal PCIe mini-card cellular modems.

Q. What is the function of the mini-USB port in C880G Series ISRs?

A. C880G Series routers have a mini-USB type B port that enables the modem to be connected to a PC and run PC-based modem provisioning and the carrier customization tool.

Q. Do the C880G Series ISRs support the Diagnostic Monitoring (DM) port?

A. C880G Series routers have removed the Diagnostic Monitoring port from the chassis front faceplate. The remote Diagnostic Monitoring function is required to collect the modem Diagnostic Monitoring log.

Q. Do the C880G Series ISRs support the National Marine Electronics Association (NMEA)?

A. C880G Series routers support NMEA. A virtual serial port is implemented to export NMEA format GPS data to external NEMA 2.0-compliant user applications.

Q. How do I configure NMEA on C880G Series ISRs?

A. To enable NMEA GPS data streaming, C880G Series routers have introduced two new command-line interfaces (CLIs): cdma|gsm gps modem standalone and cdma|gsm gps nmea. A virtual serial port has been implemented in the Cisco IOS Software to export NMEA-formatted GPS data. If end users connect the router to a Microsoft Windows-based PC through an Ethernet connection COM port emulation software is required on the PC side to emulate the COM port over the Ethernet link.

Q. What NMEA sentences do the C880G Series ISRs support?

A. C880G cellular modems support the following NMEA sentences: GGA, GSA, GSV, RMC, and VTG.

Q. How many SIM card slots do the C880G Series ISRs support?

A. C880G Series routers support two SIM card slots, which allow cellular modem failover to the secondary SIM card to continue service when the modem loses services to the primary SIM card.

Please refer to the Cisco 819 Integrated Service Router Q&A and “ Configuring Cisco EHWIC and 880G for 3.7G (HSPA+)/3.5G (HSPA)” for more information about how to use and configure dual-SIM.

Q. Is dual-SIM supported on CDMA 3GPP2 based C880G Series ISRs?

A. C880G CDMA 3GPP2 Series routers do not support the SIM card; therefore, the dual-SIM feature is not supported on these routers.

Q. How do I send, display, delete, and archive SMS on C880G Series ISRs?

A. C880G Series routers have an SMS function that enables the routers to send and receive SMS messages. This feature also enables the routers to save and store the SMS messages in an FTP server. SMS is enabled by default. You can send, display, delete, and archive SMS through the router CLI.

Q. Is encapsulation ppp supported by C880G Plus 7 Series ISRs?

A. No. C880G Plus 7 Series routers support encapsulation slip by default.

Q. What is Direct IP on C880G Plus 7 Series ISRs?

A. C880G Series routers are integrated with a Sierra Wireless MC8705 cellular modem that is running under Direct IP mode to maintain HSPA+ data throughput. Direct IP is a Sierra Wireless proprietary framing protocol used to transfer data between the host platform and the modem. Direct IP framed data have a dedicated USB connection, meaning the host can still send AT commands after the direct IP data session is established. Cisco IOS Software sets encapsulation to SLIP based on the data link protocol between the host and the modem.

Q. What WLAN antenna options are available for C880W Series ISRs?

A. All C880W Series routers embed three dual-band 2.4- or 5-GHz Planar inverted-F antenna (PIFA)-type omnidirectional antennae. External swivel-mount dipole antennae are no longer used. Antennae are attached to the cover of the chassis and covered by the front bezel, and U.FL-type RF connectors attach to the radio.

Q. Do the Cisco 880 WLAN Series routers have removable WLAN antennae?

A. Only Cisco 881 WLAN Series routers have removable swivel-mount dipole antennae. Other products in these routers have captive default dipole antennae. Removal of them and support for other types of external WLAN antenna is not supported by Cisco.
