Frequently Asked Questions
What does an expansion chassis do in a PABX system?
An expansion chassis adds capacity to your main PABX system. It provides additional slots for cards that support more telephone lines, extensions, and advanced features without replacing the entire system.
How many additional lines and extensions does this expansion chassis support?
The SL2100 Main Expansion Chassis supports up to 126 lines and 128 extensions, enabling scalability as your business grows from a small office to a larger operation.
What is the benefit of having up to two additional expansion cabinets?
Two expansion cabinets give you flexibility to grow your system in stages, adding capacity gradually rather than making a large upfront investment in a fully equipped system.
How does modular expansion protect my investment?
Instead of replacing your entire phone system when you outgrow capacity, you add expansion chassis incrementally. This spreads costs over time and protects your initial investment.
