Terminals
Type: Standardized interface device
Place of origin: CTA
A terminal is the standardized interface device through which all CTA communications, transactions, and authorizations are carried out. All terminals can use the standard terminal code.
They serve as the primary line of communication between individual workers, managers, and the wider systems of authority. Terminals are highly regulated pieces of equipment, manufactured to uniform specifications to ensure compatibility across all CTA jurisdictions.
Terminals handle data exchange, contract updates, chain broadcasts, and personal identification verification. Depending on clearance, a terminal can authorize transfers, process requests, or display higher-level directives.
While their functionality varies by model, all terminals are built to handle secure communication and cross-system standard codes without corruption.
The most efficient use of terminals is in synchronized chain route broadcasts, where information is delivered simultaneously to hundreds of thousands of devices without delay or corruption.
Terminals communicate through encrypted channels layered across CTA relay networks. They can operate on local connections or long-range inter-system relays depending on their class.
Locally, terminals link directly through short-range encrypted signals. This is most common in administrative offices, where dozens of terminals sync to a single management node. These connections prioritize speed over range, ensuring no lag in contract approvals or permit checks.
Relay networks are layered, primary long-haul relays between hubs, supported by secondary relays for periphery connections. Signals are encrypted, duplicated, and bounced through multiple channels so that disruption in one does not collapse the entire chain.
To prevent systemic failure, terminals use redundancy and failover modes, with analog verification processes in place for critical exchanges.
The most common failure is signal lag or dropped sync with the registry, which freezes transactions momentarily. Hardware rarely breaks, but when it does, it’s usually from physical damage to ports or displays. In extreme cases, memory corruption can make a terminal unable to read an ID.
They are used for everything from clocking into work, logging repair tasks, receiving chain route broadcasts, and approving permits, to accessing archival data. Terminals represent the day-to-day interface with the CTA system, and life under its jurisdiction is nearly impossible without access to one.
