Datasheet

●

Use mobile equipment personalization (MEP) unlocking, which allows locking the modem or high-speed

WAN interface card (HWIC) to a particular cellular carrier, thus allowing the carrier to subsidize the

equipment. This feature allows end users to use the modem with other carriers after the locking period is

over, as required in some geographical regions and countries

●

Use Open Mobile Alliance Diagnostic & Monitoring (OMA-DM) activation, which allows CDMA modems to

be activated and provisioned using the OMA-DM protocol

For remote-management capabilities, the Cisco 3G PCI Express Minicard Standard Form Factor F2 card

supports the Simple Network Management Protocol (SNMP) interface 3G MIB, allowing access to the

standard interface counters. The interface MIB also provides traps for interface up, interface down, and

modem presence events. (Note that a cellular MIB that allows polling of signal and network statistics is under

development.)

It supports collecting modem logs through remote Diagnostic & Monitoring capability.

The Cisco 819 supports configuration through a Cisco web-based application, Cisco Configuration

Professional.

Q. What new 3G MIB features are supported on the Cisco 819 ISRs?

A. In addition to traditional 3G WWAN, ENTITY, and IF MIB support, the Cisco 819 ISRs support 3G WWAN MIB

persistence, which allows SET objects to survive from router reloads and modem power cycle. New MIB

objects will be implemented for SMS statistics and Global Positioning System (GPS) data:

Q. What protocol is used by MC8705 modem?

A. The Sierra Wireless MC8705 modem uses direct IP protocol to transmit packets between Cisco IOS Software

and the modem. The cellular interface created for the HSPA+ modem is hardcoded with “slip” encapsulation to

differentiate from the existing GSM/HSPA modems, which have a Point-to-Point Protocol (PPP) link to Cisco

IOS Software. The migration to direct IP is mainly directed by the increase in data throughputs. The 4G/LTE

modems are also direct IP-based protocol. Please refer to the Configuring Cisco EHWIC and 880G for

3.7G/3.5 configuration guide for more information about how to configure MC8705-based Cisco 819 ISRs.

Q. How can I debug direct IP sessions in the Cisco 819HG+7 and 819HGW+7 ISRs?

A. Execute the debug cellular 0 message callcontrol command to debug direct IP call setup and termination.

Q. Does the Cisco 819 support SIM online insertion and removal (OIR)?

A. No. The SIM slots are located under the chassis and protected by the SIM access panel. Please refer to

Cisco 819 Integrated Service Router Hardware Installation Guide for installation of retention lock.

Q. When does SIM switchover happen?

A. The Dual SIM feature implements auto-switch and failover between two cellular networks. The switch is

controlled by a failover timer. The failover timer starts when the modem powers up or changes service status

from normal to others. When the failover timer expires, the modem switches from the primary slot (default is

slot 0) to the secondary (failover) slot (default is 1). When switchover happens, the modem is power cycled to

activate the new SIM. The default failover time is 2 minutes. The maximum number of retries is 10. Please

refer to the configuration guide for more details:
