Meet-me room - Wikipedia
The meet-me room (MMR) is typically found with the data center, both for predominantly Fiber Optic services but also coaxial and twisted pair. Zayo Takes Over 60 Hudson Meet-Me-Room.

Carrier-neutral centers however, are rich in interconnection. A benefit of being a customer in One Wilshire's MMR is that one can bring their own fiber into the building or they can.
In this scenario the MMR is split for security reasons between tenants and carriers. Tenants are permitted in their side of the MMR, and carriers in theirs. As with other options, this approach could increase the amount of conduit in the ceiling space and quickly limit future installs.
Additionally, it could pose a security concern to all building tenants. Using a third-party cross-connect provider as the only staff permitted in the customer side of the MMR should limit these concerns. Direct connect—extended demarcation—This means each carrier connects directly with the client from the carrier-equipment rack in the MMR to the client-side demarcation point in the tenant space see figure, illustration 2.
In this scenario the multiple conduits demanded by tenants can quickly fill any available space above the ceiling. Consider using flexible armor cable as an alternative to rigid conduit. Although some tenants want this service, some do not. Cross-connect in the MMR—In this scenario, each tenant space has pre-installed patch panels located in a secure side of the MMR whereby multiple carriers cross-connect see figure, illustration 3.
Some tenants may express security concerns with this topology, and carriers may not like the potential that a competitor could accidently unplug their patch. If the MMR is professionally managed which is highly recommendedhowever, the carrier would not have access to this side of the MMR, ameliorating this concern. Drawbacks include higher upfront costs to carriers and operators, who may never connect to every tenant, and loss of operator cross-connect fees, again assuming that charging for cross-connections is part of the business model.
The MMR cannot be viewed as a free space for carriers and tenants to cross-connect at will. The best method of managing the MMRs is to create in-building standards and include them in every lease agreement.
Additionally, carrier agreements should include adherence to your standards.

These standards need to outline access-control, cross-connect, interconnect, and direct-connection means and methods, as well as installation and pathway standards, cable count and color standards, and labeling criteria. Examples of a few of these in-building standards include the following: Access control—Control access to carrier sides and, if designed, tenant sides of the MMRs.
Only permit third-party MMR management companies to have access to both rooms. Make sure this access is authorized, authenticated and audited. This may not sound like something that occurs, but it certainly does.
Most cities have companies offering this service, and if not, a good cable installer can be assigned to the task of managing the MMR as long as the standards are well documented and SLAs between that company and the operator exist. Pathway standards—The space above the ceiling is not limitless; as such, controls must be put in place to ensure large and typically unused conduits are not positioned between data connection points. Traditional cable tray is a sure means of transporting media; most tenants will claim that cable trays are an inherent security risk, however.
The use of flexible armored cable is something all operators should consider. It is lightweight, able to bend and ultra-thin compared with conduit.
What is a Meet-Me Room? It's the Most Important Room in Your Data Center
Color codes—Color coding the media is a best practice for many reasons. Colors can designate fiber-types, counts, installation dates and specific client connections. Mining out the infrastructure of past tenants is easy once the cables are identified, and identification by color is a quick means of disposal.
There have been many painful lessons and very public displays illustrating the ramifications of poor management of data center spaces.
The two do not mix well for obvious reasons, so designing the EF is key to a successful space. How do you want to make your MMR secure? Who will be granted access, and at what level will the access be granted?
All security measures should be considered at different levels, from IP Cameras to biometrics at room and rack level.
There are many options, but the main consideration is that the security fits the profile of the customer services it is protecting.
We should also consider latency. Minimal connection points improve service; however, not providing managed connection points for the infrastructure will also increase the risk of poor cabling practices and overloading conveyance systems.
This is the homerun versus structured cabling debate which could itself be a whole other blog. Essentially, minimal performance gains can potentially increase downtime in the future due to poor practice and overloading. This needs clear direction as future refurbishment projects are challenging and time-consuming to complete, i. If we can avoid such projects with good initial design practices then we should strive to do so.
Other considerations would include: How many MMRs are required for redundancy: Internal containment systems to connect the zones and client space. A clear administration system for conveyance and cabling. Ensuring codes are met and standards are achieved. Yes, we are just as important as the design itself. Not to mention an understanding of designing in conjunction with other disciplines and the limitations of what the environment can provide.
