A while back we published this video above on setting up the Adtran Total Access 908e as an FXS gateway. To recap a little, an FXS gateway allows you to connect analog phones or stations, to a VoIP based system. It does that by providing an analog interface like an FXS port to which you connect your analog phone, and through the use of witchcraft, translates the signal from analog to digital.

To clarify a little bit more if you’re new to this technology: when we talk about analog gateways, we are generally referring to two types of interfaces, or ports; FXS and FXO.

FXS stands for foreign exchange station, but to get to the points, it’s what PROVIDES dial tone to a device like a credit card machine, fax machine, or an analog phone.

FXO stands for foreign exchange office, and RECEIVES dial tone. An example of an FXO port would be on a modem.

So say it with me, FXO PROVIDES dial tone, FXO RECEIVES dial tone. It’s Easy!

Now that we’ve gotten that out of the way, let’s talk about hotlining. Hotlining is when an FXS port automatically dials a predetermined number when off hook. You’d see this sort of setup on common are phones (door entrances, hallways, lobbies, etc.), or in elevators. The idea is simple: restrict what the user can do with the phone.

To achieve this on an Adtran Total Access 908e, it’s simple, sort of. You can configure roughly 90% of the Adtran Total Access 900 Series devices through the graphical user interface, but there are some nifty features hidden in the command line, like hotlining! The good news is configuring a hotline using the command line is about as complex putting on your own socks.


First some prerequisites:

  1. Make sure your dial plan is configured to accept the digits you plan on calling when your FXS port goes off hook.
  2. Have a trunk group also accepting the digits and have a trunk to send the call to.
  3. Know your current, or default passwords.

Let’s go:

As an example, we’ll create a user “5000” and configure a hotline for that user on FXS 0/1 to dial 716-867-5309 when off hook.

  1. Log in and create the user: Got o Users Accounts and fill out some basic information such as first, last name, and select “Analog Station” as Phone Type. Select FXS 0/1 and click Apply. adtran-image1
  2. SSH or Telnet into the Total Access 908e and configure the hotline using the following syntax:adtran-image2
  3. Check your configuration using “show run” or “do show run”. It should look like this:adtran-image3

Now, when any device connected to FXS 0/1 goes into an off hook state, the Total Access 908e will dial 716-867-5309. I told you it would be easy.

To be honest, the Adtran Total Access 900 line is capable of a lot more, and it’s one of my favorite pieces of equipment. Not to overuse the term, but I consider it the true Swiss Army Knife of the telecommunications world. Learn more about it by visiting Adtran’s site, or calling VoIP Supply at 1-800-398-8647.

Happy VoIPing!


The NetVanta Series is a comprehensive portfolio of enterprise-class networking equipment designed to cut costs in your network without compromising performance. Recently, ADTRAN released a new NetVanta family member – the NetVanta 3140, a fixed-port, high-performance Ethernet router supporting converged access and high-quality voice services.

This brand new router is an excellent selection for fast-growing small-to-mid-sized businesses looking for a fast, easy, and extremely flexible solution. It is ideal for carrier-bundled service offerings, and enterprise class Internet access for secure, high-speed, corporate connectivity. Let’s see what hot features it has to offer!


Top 5 Benefits of The NetVanta 3140

#1 Flexibility and Redundancy

The NetVanta 3140 is ideal for multiple applications where Ethernet redundancy is needed given the three Gigabit ports that can be either LAN or WAN facing. This solution also features a USB interface that can be used for 3G/4G backup. If your deployment still separates voice and data network, the NetVanta 3140 will be a perfect fit with a single WAN link and the other two Gigabit interfaces.

#2 Feature-rich ADTRAN® Operating System (AOS)

The ADTRAN Operating System (AOS) allows for the support of static and default routes, demand and policy based routing, and provides fast, accurate network convergence using routing protocols such as BGP, OSPF, RIP, and PIM Sparse Mode for multicast routing.

The AOS provides a powerful inspection firewall that can protect against common Denial of Service (DoS) attacks like TCP syn flooding, IP spoofing, and more. Its Web-based GUI comes with step-by-step configuration wizard, management capability, and the ability to upload firmware updates.

#3 Enterprise Session Border Controller (eSBC)

As having an eSBC became mandatory for most VoIP deployments, the NetVanta 3140 also includes an optional eSBC to secure and troubleshoot your SIP to SIP communications. This featured eSBC builds strong, robust network security and enables voice interoperability, delivering a truly converged application platform at the customer premises.

#4 Voice Quality Control

The NetVanta 3140 uses Low Latency Queuing, Weighted Fair Queuing (WFQ), Class-based WFQ, and DiffServ marking to prioritize mission-critical traffic and control network congestion. It also deploys Voice Quality Monitoring (VQM) to capture, MOS, jitter, delay, and packet loss statistics to troubleshoot VoIP calls over the WAN. This diagnostic tool is extremely valuable because it isolates the network issues in real-time and ensures superior call quality at all times.

#5 VoIP Ready

The NetVanta 3140 highlights a specialized SIP ALG that allows SIP traffic to traverse NAT-enabled firewalls. This interoperability allows IP PBXs, phones, and other SIP-based devices to set up, tear down, and pass voice and call control messages seamlessly through the integral NAT-enabled firewall. In combination with the QoS and VQM features, the NetVanta is truly VoIP ready and is available as either a desktop or rack-mountable platform.

If you spend a great deal of time deploying VoIP systems or building IP networks for various customers, you quickly learn to appreciate things that just seem to work. What I mean by that is, there’s no crossing your fingers, or sacrificing a virgin to have a piece of equipment work the way it’s actually supposed to.

If you’ve been reading some of my posts or have seen the videos that I have been in, then all of you know that I am a bit of an ADTRAN fanboy. I like ADTRAN the same way that I like my 22-year-old Swiss Army KnifeⓇ. It’s reliable, well-made, fits in your pocket, and will always get the job done. With that, let me re-introduce you to the ADTRAN NetVanta 1531P. For my first introduction to the NetVanta 1531P, check out my unboxing video here. Also see the configuration video below:

A key aspect that I’d like to spotlight on this switch is ADTRAN’s “VoIP Setup Wizard” feature. Setting up the LAN for voice is challenging, because of the complexity involved with configuring various settings such as Quality of Service (QoS), V-LANs, Class-of-Service (CoS), uplink ports, among others. With ADTRAN’s VoIP Setup Wizard, the whole process is automated to just two-clicks and your LAN is setup for voice. This is ideal if you have a voice over IP phone system or are thinking of switching to VoIP, which allows for fast VoIP deployments. ADTRAN offers a number of “voice aware” features that simplify setup and management of your voice deployments.

The NetVanta 1531P won’t actually fit in your pocket (unless you still wear Jenco jeans) but it has a fantastic form factor that allows you to mount or set it just about anywhere in your organization. Yes, it is a small capacity switch with 12 ports, which means it’s meant for small deployments of VoIP phones or wireless access points, but I’ve found that it really shines as a test or provisioning bench switch. The 1531P can function as a DHCP server, which is not a feature readily found in the lesser “prosumer” class of switch in the same-ish price point (under $600). This is important because you can serve IP addresses to IP phones without the need for a dedicated piece of equipment such as a router or server. You can of course consequently serve DHCP options, such as option 66, to point phones to a specific TFTP server. A customer’s environment can easily be replicated by creating an additional VLAN with their specific IP address scheme, default gateway, and DNS information allowing you to configure both phones and even an IP PBX to be shipped pre-configured, which is the actual method used by VoIP Supply for provisioning services.


Okay, how about some more details? Well, it’s a small, lightweight, fanless, PoE switch, and it’s a layer 3 device. Actually, layer 3 light as described by ADTRAN, which means it can perform static routing (VLAN to VLAN) but is limited to how many static routes you can use (16). It cannot perform dynamic routing like the NetVanta 1544 for example, but there are some pretty big differences in the price point when making that comparison (by a few thousand). The NetVanta 1531P sports 8 PoE and PoE+ ports which produce up to 30 watts per port (PoE+) with a maximum PoE budget of 65watts. In terms of IP phones, it’s plenty to support 8 PoE powered phones as they aren’t as demanding as wireless access points, but do your research and make sure you are accounting for all devices needing power. There are an additional 4 ports on the 1531P, two are non-PoE Ethernet, and two SFP, all of which are 1 Gbps. There is a console port accessible via a DB-9 RS-232 port that connects you to a very familiar command line interface. If you have any command line experience with Cisco, then you’ll feel right at home with ADTRAN as the syntax is nearly identical. Of course, you can SSH for the same experience, but you are also provided a web-based interface which means you’ll almost never have to SSH or console into the switch if you are a little rusty on your command line witchcraft. For a complete list of the NetVanta 1531P check out the datasheet.

adtran-logoADTRAN’s standard web interface that you find with all of their NetVanta and most TotalAccess products provides you with an efficient avenue to administer your switch. It isn’t overly garnished with tacky graphics or is so convoluted that it becomes a frustrating experience if you don’t already know the ins and outs. The web interface is, just right, and leaves out virtually nothing. There are some tasks that are moderately quicker via the command line, but as stated before, the user interface can accomplish all of the most common switch administrative tasks without needing to use the command line. It also doesn’t change its appearance, ever. Changes or added features are subtle and go almost unnoticed if you didn’t read the latest firmware release. This isn’t necessarily a bad thing, as I tend to place value on consistency and general standardization. Speaking of firmware, it’s free, for the life of the product. Yes, I said FREE. Firmware can be downloaded from ADTRAN after you create a login with them, which is also at no cost to you.

If you think you have a need for a small layer 3 switch that can provide PoE to IP phones or any other compatible device, give VoIP Supply a call. The ADTRAN NetVanta 1531P goes to the top of my recommendations list for battle proven, reliable, and feature-rich equipment.

ADTRAN is a unique company; instead of replacing models, they simply make their existing models better.

ADTRAN’s most recent release is the third generation of the Total Access 900e IP Business Gateways. If you’re not very familiar with ADTRAN, stay tuned; for the people who are familiar with ADTRAN, rest assured all the old Total Access 900e features are still included, and then some.

Adtran TA 900e Series

Total Access 900e IP Business Gateways are known as carrier-class gateways. A traditional service provider such as AT&T or Verizon use TDM switches for their services, and to transform those signals into IP service, you’ll need a gateway with a T1 interface. Here is where ADTRAN comes in. The Total Access line had previously offered a T1 interface, FXS ports, and a single Ethernet interface which gave users IP capability to their existing legacy equipment, along with data connectivity and VoIP functions such as Voice Quality Monitoring and Quality of Service. ADTRAN also integrated a full featured IP router which provided the gateways with this data routing and Internet connectivity. Users could expect the gateway to perform stateful inspection firewall for security and have dynamic bandwidth allocation.

Now take all those features and add-on these:

  • 66% performance increase in router performance
  • Better enabled bandwidth for faster services at 100 Mbps
  • Multiple T1 interfaces: Quad T1/FT1 and RJ-48C and USB 2.0
  • 3 Ethernet interfaces: 1 Gigabit and 2 Fast
  • Hardware-based Network Address Translation (NAT) for IP address concealment and security
  • Supports 802.1q Virtual LAN (VLan) Trunking
  • Optional Enterprise Session Border Control (eSBC) with an additional upgrade
  • Optional outbound FXO lifeline for improved flexibility with hardware configuration

These are just a few of the dozens upon dozens of features of the Total Access 900e Gen 3 IP Business Gateways. Chris Thompson, director of product management for ADTRAN, stated in their press release: “As carrier experts continue to choose ADTRAN for their network, we have raised the bar on the performance and features of the Total Access 900e to address new applications and capabilities needed to take high-performance networks to the next level.”

ADTRAN does it right by maintaining a good product and updating the line when it’s beneficial to the customer. In a world of changing technology, it’s key to have a device that can manage the transition from aged-out analog equipment to VoIP hardware. The Total Access 900e Series can keep your fax machine running while supporting VoIP phones smoothly. If you’re looking for flexibility and scalability, Adtran might be the perfect route for you.
