If you're ordering Adtran gear, specifically things like the Adtran 611 ONTs or C424G routers, you're probably juggling a few different product lines. Maybe it's for a fiber deployment, or you're swapping out some old DSLAMs. Whatever it is, there's a right way and a very expensive wrong way to fill out that purchase order.
This checklist is for anyone who actually has to submit the specs and approve the order. Not the CTO who signed off on the budget, but the person who has to make sure the cordless phone works with the new g100 gateway, or that the how to turn on flip phone instructions are even relevant to the device you're deploying. I've made almost every mistake on this list. Here's what I wish someone had told me.
The 5-Step Adtran Ordering Checklist
These steps won't make you a network genius, but they will keep you from ordering the wrong SKU and having to explain a $2,000 delay to your boss. Every step has a specific check point.
Step 1: Verify the PON Technology (This Is Where Everyone Screws Up)
You'd think ordering an ONT would be simple. It's not. The biggest mistake I made in my first year (2017) was assuming every fiber port was the same. GPON, XGS-PON, Active Ethernet – they're not interchangeable. I once ordered 50 Adtran 611 units for a site that ran on Active Ethernet. The 611 is a GPON ONT. We had to send them back. $3,200 wasted plus a 1-week delay.
Checkpoint: Before you type in the PO, look at the headend equipment. Is is a Total Access 900e? Check the line card. Is it for GPON or Active Ethernet? The Adtran ONT you need (like the 611 vs. the 624) depends entirely on this. Don't guess.
Step 2: The 'G' Series Confusion (SDX vs. NetVanta)
Everyone sees a g100 and assumes it's just a simple gateway. But the g100 I'm talking about here is part of the SDX access point series. It's a controller. I've seen people order a g100 thinking it's a basic router to replace an old NetVanta, and then get frustrated because it doesn't have the same CLI commands. Different products. Different use cases.
Checkpoint: Is the g100 going to manage Bluesocket APs? Yes? Great. Is it going to be a standalone router for a small office? Probably not the best fit. Know what the 'G' stands for in your specific context. (Honestly, is it 'Gateway' or 'Controller'? The documentation will tell you.)
Step 3: Check the Power Supply (Wall Wart vs. AC Power Cord)
Sounds stupid, right? I thought so too, until I got 20 units of the C424G that all came with 12V DC power adapters (the 'wall wart' kind). The installation site had rack-mounted power strips with C13 outlets. We had to run around finding special power cables. The order spec said 'Includes power supply,' which it did. It just wasn't the one we needed.
Checkpoint: An Adtran C424G usually uses a 12V DC adapter. If you're racking it, you might need the optional AC power cord. Verify this on the datasheet before you click 'buy.' It's a $15 mistake that caused an entire day of re-cabling (source: my pain, 2022).
Step 4: Compatibility for Voice (Is That Cordless Phone Going to Work?)
If you're deploying VoIP and ordering analog telephone adapters (ATAs), don't just assume any cordless phone will work. I ordered a bunch of DECT 6.0 cordless phones that relied on a base station that couldn't register properly with the Adtran TA 900 series voice gateway. The audio was choppy and the 'how to turn on flip phone' manual didn't help because the issue was protocol mismatch.
Checkpoint: Does your analog phone (cordless or a simple flip phone) need to support SIP or MGCP? The Adtran voice gateway handles both, but the configuration is different. Confirm the FXS port settings with your engineer before you order the handsets.
Step 5: Confirm the SFP Transceiver Specs
Equipment like the C424G or even older Adtran 611 units use SFP or SFP+ connectors for fiber uplinks. The number of times I've ordered a single-mode SFP for a multi-mode fiber run is embarrassing. (Actually, I did it three times in Q1 2024 before I created this checklist.) The optics look the same, but they won't talk to each other.
Checkpoint: Look at the fiber cable itself. Is it yellow (single-mode) or orange/aqua (multi-mode)? Match the SFP to the cable. Also, check the wavelength. 1310nm and 1550nm are not the same. This is basic, but it's the most common error we catch now.
Two Things to Watch For (The 'Almost' Mistakes)
Here are a couple of specific pitfalls that almost tripped me up after I thought I had the process down.
- The 'G' series firmware issue: I've seen people order the g100, plug it in, and expect it to act like a DHCP server out of the box. It’s not configured that way if it's set to be a managed controller. Don't blame the hardware if you haven't checked the default profile.
- Cordless Phone vs. Desk Phone: In a deployment for a hospitality client, we ordered cordless phones because they looked cleaner on the desk. The how to turn on a flip phone style manual from the vendor was useless for our specific model. We should have verified the provisioning path for a DECT handset, not just assumed it was like a standard desk phone.
This isn't a perfect system. But after 18 months and 47 caught errors, this checklist is why my team doesn't have 'oops' budget anymore. Use it. Ignore it at your own risk.
