# Sequans Monarch (group)

**Module:** **[Supported Modules](group__group__supported__modules.html)** **/** **[Sequans](group__group__sequans.html)** **/** **[Sequans Monarch](group__sequans__monarch.html)**
Manufacturer: Sequans. Models: Monarch.

## Connection Information

- Combined TCP/SSL sockets:
  - 6
  - Unlike most modules, the sockets are numbered starting at 1, not 0.
- SSL contexts (security profiles):
  - 6
- Socket Buffering:
  - The modem has an internal buffer for incoming data.
- Socket Numbering:
  - The modem respects user-specified multiplexing channel numbers/identifiers for socket connections.
