Powerful Cisco ISR 1941W Review

• To simulate a small branch office, the Cisco ISR
  1941W was configured as a branch router serving a
  dozen employees. Primary network connectivity was
  established via a public internet connection with
  a DMVPN (Dynamic Multipoint Virtual Private
  Network) encrypted link to corporate
  headquarters. A 3G wireless data connection was
  setup for branch redundancy in the event of a
  primary WAN link failure. The CISCO1941/K9 was
  also configured to support wireless utilizing
  802.11n radio to extend the corporate wireless
  network into the branch office as well as provide
  guest network connectivity for visitors to the
  office. Security featuresZone Based Firewall,
  Cisco IOS IPS and content filtering were
  activated. The Voice services were provided by a
  headquarters-based CUCM (Cisco Unified
  Communications Manager).

Medium Branch Office Cisco ISR 2911 Platform

• A medium branch office deployment was simulated
  using a Cisco ISR 2911. This branch scenario
  supports about 25 users. Primary and backup
  network connections were to be provided by two
  separate Ethernet WAN links. An IP WAN provided
  primary network connectivity with a DMVPN secure
  connection serving as backup to corporate
  headquarters. Security featuresZone Based
  Firewall, Cisco IOS IPS were activated. Voice
  services were provided by a headquarters-based
  CUCM with local POTS (Plain Old Telephone
  Service) access from the CISCO2911/K9 . Cisco
  Unified SRST (Survivable Remote Site Telephony)
  was supported to provide redundant local call
  control in the branch offices in the event the
  central CUCM is unreachable. Telepresence and
  video are also supported and enabled for this
  deployment.

Large Branch Office Cisco ISR 2951 Platform

• A large branch with 40 to 60 users was created
  using a Cisco ISR 2951. In this scenario, the
  2951 was configured to provide both primary and
  backup corporate access via an IP WAN connection
  as the primary connection to the headquarters and
  a public Internet connection with a DMVPN secure
  connection acting as backup. In this scenario the
  Cisco 2951 was configured to support all voice
  functions including Cisco Unified Communications
  Manager Express (CUCME) for call control and
  voice-mail with Cisco Unity Express. Local PSTN
  access is provided by a SIP trunk from the 2951
  to the local phone network. Zone Based Firewall,
  Cisco IOS IPS and Cisco WAAS were also activated
  in the router.

Regional Branch Office Cisco ISR 3945 Platform

• A large regional office with 150 or more
  employees was simulated with a Cisco 3945 .
  Primary and backup connectivity to the
  headquarters was provided with redundant IP WAN
  connections. The 3945 was configured to support
  CUBE (Cisco Unified Border Element) functionality
  for call control in conjunction with a CUCM at
  corporate headquarters. SRST functionality was
  also enabled at the 3945 router in the event that
  connectivity with the central CUCM is lost. Local
  PSTN access was provided by a SIP trunk to the
  local telephone network. Zone Based Firewall,
  Cisco IOS IPS and Cisco WAAS were also activated
  in the router.
