Integrated T1
An Integrated T1 is a channelized T1 line that splits a single circuit between dedicated internet bandwidth and a block of voice phone lines. One point to point T1 connection runs both data and dial tone, so a small or medium office gets internet and telephone over the same managed link. It is the efficient way to serve a building that needs both without ordering two separate circuits.
How an Integrated T1 works
An Integrated T1 divides the 24 channels of a T1 line between data and voice. Some channels are bonded for dedicated internet bandwidth while the rest are provisioned as phone lines, often as a PRI group. The split can be tuned to your mix of users and call paths, and the carrier delivers it all over one point to point T1 connection to your office.
Typical Integrated T1 pricing
When it fits
✓ Great fit
Small and medium offices of roughly 5 to 30 users that need both internet and phone service and want to consolidate them onto one dedicated T1 connection. It fits businesses that value a single managed point to point link, one bill, and a flexible split between data bandwidth and voice channels.
● Consider instead
If you need heavy bandwidth, a data-only full T1 or bonded T1 lines free the channels otherwise used for voice. If your phones are moving to the cloud, pairing dedicated internet with SIP trunking can be more flexible than fixing voice channels on the T1 line.
How it compares
An Integrated T1 reserves some channels for phone lines, while a full T1 connection dedicates all 24 channels to data.
An Integrated T1 splits the circuit between internet and voice, while a Voice T1 dedicates every channel to phone lines.
An Integrated T1 carries voice and data together, while a Fractional T1 lights only data channels on the T1 line.
What to look for
- ✓Channel split. Decide how many channels go to dedicated internet versus voice lines on the Integrated T1.
- ✓PRI for voice. Confirm whether the voice portion is delivered as a PRI group and how many call paths it supports.
- ✓One managed circuit. An Integrated T1 connection means a single point to point link and one provider for both services.
- ✓Scaling the mix. Ask how the data and voice split can be re-provisioned as your user and call counts change.
Common questions
What is an Integrated T1?
An Integrated T1 is a channelized T1 line that splits one circuit between dedicated internet bandwidth and a block of voice phone lines.
Can one T1 line carry both internet and phone?
Yes. An Integrated T1 connection dedicates some of the 24 channels to data and the rest to voice, so both run over a single point to point link.
How many users does an Integrated T1 support?
It commonly serves 5 to 30 users plus voice, with the exact mix set by how the channels are divided between data and phone lines.
How much does an Integrated T1 cost?
An Integrated T1 typically runs a few hundred to about $1,200 per month depending on the data and voice split and the number of lines.
Is the voice on an Integrated T1 a PRI?
Often yes. The voice channels are frequently provisioned as a PRI group on the same T1 line that carries your internet.
Is an Integrated T1 dedicated?
Yes. Both the data and the voice channels on an Integrated T1 connection are dedicated to your business on a point to point circuit.
More on Integrated T1
An Integrated T1, sometimes called a channelized T1, takes a single T1 line and divides its 24 channels between dedicated internet bandwidth and voice phone lines. That lets a small or medium office run both data and telephone over one point to point T1 connection instead of buying separate circuits for each. The split is flexible: a few channels can be reserved as phone lines while the rest are bonded for internet, and the balance can be tuned to how many users and how much call volume the business has. Because every channel is dedicated, both the internet and the voice service get reserved capacity with a service-level agreement.
Consolidating onto one Integrated T1 connection means a single provider, one bill, and one managed link to support. The voice portion is commonly delivered as a PRI group, giving the office real phone lines alongside its dedicated internet. For a growing business, the data and voice mix can be re-provisioned over time, and when bandwidth needs outpace the T1 line, the natural next steps are a fractional or full data T1 paired with separate voice.
Types of serviceOptions and variants
What businesses use it for
- ✓Office internet and phones. An Integrated T1 runs dedicated internet and voice lines for a 5 to 30 user office over one circuit.
- ✓Single managed connection. Consolidate data and telephone onto one point to point T1 line with a single provider and bill.
- ✓Branch consolidation. A remote site gets both services on one dedicated T1 connection instead of two separate circuits.
- ✓Small business PBX. The voice channels trunk a PBX while the data channels deliver dedicated internet.
- ✓Flexible data and voice split. Re-provision the channel mix as the business adds users or call paths on the same T1 line.
