ADTRAN NetVanta 3120 with Dial Backup

ADTRAN produced NetVanta 3120 variants with Dial Backup, commonly abbreviated DBU.

Dial-backup functionality was designed to provide an alternate communications path when the primary WAN connection became unavailable.

Organizations replacing a DBU-equipped 3120 should determine whether the original backup method is still required or whether a newer Ethernet, broadband, or cellular failover design would better meet current requirements.

ADTRAN NetVanta 3130

The ADTRAN NetVanta 3130 is another fixed-port router in the historical NetVanta 3100 Series.

NetVanta 3130 systems were designed for business access routing and can remain present in branch offices, enterprise networks, service-provider deployments, and other installed-base ADTRAN environments.

Replacement planning should account for:

• WAN connectivity
• Routing requirements
• Firewall policies
• VPN requirements
• Backup connectivity
• Software configuration
• Current internet bandwidth

ADTRAN NetVanta 3130 with Dial Backup

ADTRAN also produced NetVanta 3130 configurations with Dial Backup.

The current NetVanta 3140 documentation includes eBGP and iBGP capabilities.

ADTRAN VRRP

Virtual Router Redundancy Protocol can provide gateway redundancy in supported network designs.

VRRP allows multiple compatible routers to participate in a resilient gateway architecture.

ADTRAN Policy-Based Routing

Policy-based routing allows traffic to be forwarded according to administrator-defined policies rather than relying solely on the normal routing table.

This can be useful when different applications, networks, or traffic types need to use different WAN paths.

ADTRAN NetVanta 3100 NAT

Network Address Translation allows devices using private IP addresses to communicate with external networks.

NAT remains a fundamental feature in many business internet-access deployments.

ADTRAN NetVanta 3100 Support

Support availability depends on the exact NetVanta model, lifecycle status, geographic location, and manufacturer service program.

Organizations maintaining older 3120 and 3130 equipment should evaluate current support availability alongside replacement planning.

Replacing an ADTRAN NetVanta 3120

Before replacing a NetVanta 3120, document the existing router configuration.

Important details include:

• Model and part number
• WAN interface
• Dial-backup configuration
• LAN addressing
• Firewall policies
• VPN
• Routing protocols
• AOS configuration

Replacing an ADTRAN NetVanta 3130

A NetVanta 3130 replacement should provide the interfaces and software capabilities needed to reproduce or improve the existing network design.

Do not select a replacement solely according to Ethernet port count.

Replacing an ADTRAN NetVanta 3140

When replacing a 3140, verify whether the deployment uses:

• All three routed Gigabit interfaces
• USB cellular access
• VPN
• Voice Quality Monitoring
• eSBC software
• Dynamic routing
• Rackmount or desktop installation

Upgrading from a NetVanta 3120 or 3130

Organizations upgrading an earlier 3100 Series router should compare the old WAN design with current connectivity requirements.

An upgrade can provide an opportunity to evaluate:

• Higher internet bandwidth
• Gigabit Ethernet
• Cellular failover
• Modern VPN requirements
• VoIP and SIP services
• Updated routing architecture
• Current support availability

NetVanta 3100 Series vs. NetVanta 3000 Series

The terminology can be confusing because ADTRAN historically used the NetVanta 3100 Series name for fixed-port routers including the 3120, 3130, and 3140.

ADTRAN's current product portfolio uses the broader NetVanta 3000 Series name for the current 3140 and 3148 platforms.

This category focuses specifically on the NetVanta 3100 Series name and installed-base router families, while newer NetVanta 3000 Series products can also appear elsewhere within the broader ADTRAN router hierarchy.

NetVanta 3140 vs. Older NetVanta 3100 Routers

The current NetVanta 3140 differs significantly from earlier 3120 and 3130 platforms.

Modern 3140 capabilities include:

• Gigabit Ethernet routing
• USB cellular connectivity
• Current business-routing software
• Optional IPsec VPN
• Optional eSBC
• Voice Quality Monitoring

Organizations replacing an older router should verify configuration compatibility rather than assuming a direct one-for-one migration.

How to Choose an ADTRAN NetVanta 3100 Series Router

Identify the Existing Model

Determine whether the deployment uses a NetVanta 3120, 3130, 3140, or another related configuration.

Check the WAN Connection

Document the primary and backup WAN technologies currently in use.
