Feature Benefit
Cisco Router and Security Device
Manager (SDM)
●
This intuitive, easy-to-use, Web-based device-management tool is embedded
within the Cisco IOS Software access routers; it can be accessed remotely for
faster and easier deployment of Cisco routers for both WAN access and security
features.
IP Telephony Support—Features and Benefits
The Cisco 2800 Series allows network managers to provide scalable analog and digital telephony
without investing in a one-time solution (refer to Table 4 for more detail), allowing enterprises
greater control of their converged telephony needs. Using the voice and fax modules, the Cisco
2800 Series can be deployed for applications ranging from voice-over-IP (VoIP) and voice-over-
Frame Relay (VoFR) transport to robust, centralized solutions using the Cisco Survivable Remote
Site Telephony (SRST) solution or distributed call processing using Cisco Call Manager Express
(CME). The architecture is highly scalable with the ability to connect up to 12 T1/E1s trunks, 52
foreign-exchange-station (FXS) ports, or 36 foreign-exchange-office (FXO) ports.

Feature Benefit
IP Phone Support
●
Optional support for Cisco in-line power distribution to Ethernet switch network
modules and HWICs can be used to power Cisco IP phones.
EVM Module Slots
●
Extension Voice Module Slots, available only on the Cisco 2821 and Cisco 2851,
provide support for the Cisco High-Density Analog and Digital Extension Module
for Voice and Fax, providing support for up to 24 total voice and fax sessions
without consuming a Network Module Slot.
PVDM (DSP) Slots on Motherboard
●
DSP (PVDM2) modules deliver support for analog and digital voice,
conferencing, transcoding, and secure Real-Time Transport Protocol (RTP)
applications.
Integrated Call Processing
●
Cisco CME is an optional solution embedded in Cisco IOS Software that
provides call processing for Cisco IP phones. Cisco CME delivers telephony
features similar to those that are commonly used by business users to meet the
requirements of the small to medium-sized offices.
Integrated Voice Mail
●
Support for up to a 250 mailboxes using the Cisco Unity
®
Express voice
messaging system is possible with the integration of an optional voice-mail AIM
or network module.
Broad Range of Voice Interfaces
●
Interfaces for public switched telephone network (PSTN), private branch
exchange (PBX), and key system connections include FXS; FXO; analog direct
inward dialing (DID); ear and mouth (E&M); Centralized Automated Message
Accounting (CAMA); ISDN Basic Rate Interface (BRI); and T1, E1, and J1 with
ISDN Primary Rate Interface (PRI); QSIG; E1 R2; and several additional
channel-associated-signaling (CAS) signaling schemes.
Survivable Remote Site Telephony
(SRST)
●
Branch offices can take advantage of centralized call control while cost-
effectively providing local branch backup using SRST redundancy for IP
telephony.
Wireless Support—Features and Benefits
The Cisco 2800 Series can provide a complete wireless solution for branch offices, small/medium
sized businesses, and Wi-Fi hotspots. Wireless services enable greater mobility for employees,
partners, and customers, resulting in increased productivity.

WLAN Connectivity
●
The 802.11b/g or 802.11a/b/g HWIC access point interface card can be used to
provide integrated WLAN connectivity to mobile clients at sites requiring a single
access point, resulting in mobility and enhanced productivity for users.
●
Dual RP-TNC connectors enable diversity and allow for optimum coverage
through the use of external antennas.
