Challenges
ATMs must stay reachable for authorizations and telemetry across mixed venues where venue LANs are unavailable or untrusted. Operators need a secure, consistent network path that supports segmentation, encrypted tunnels, and predictable failover without frequent site visits.
Expected Outcomes
A dedicated cellular or cellular-backup connection per ATM, with policy-driven VPN access, clear separation from the cardholder data environment to assist with PCI DSS compliance, and fleet-wide monitoring. Uptime improves, support tickets shorten, and change control becomes repeatable.
Click, collect, and keep moving
Every withdrawal, balance check, or cardless cash event depends on the ATM being online. In malls, branches, transit hubs, or forecourts, venue networks vary and local policies change. Relying on “whatever LAN is available” invites downtime and complex exceptions.
Placing an R2011 inside the ATM cabinet gives you a clean, controllable path for transactions and management traffic. Dual-SIM cellular provides independence from venue LANs; Ethernet WAN can be used where a trusted fixed line exists. Encrypted tunnels and standard firewall controls keep traffic scoped and auditable, while RCMS provides the estate-level visibility operations teams need.
Business Challenges
Banks and ATM operators balance availability, security, and service cost. The recurring problems are practical variable sites, tight SLA targets, and the need to prove control without rolling trucks.
- Availability across sites: Kiosks and lobbies differ; some forbid third-party devices on the LAN.
- Security architecture: Traffic must be encrypted and segmented in line with payment-network expectations; changes must be auditable.
- Failover certainty: If a primary link degrades, the ATM must switch quickly to a working path.
- Remote support at scale: Logs, config, and updates should be handled centrally to cut site visits.
- Cost control: Data plans, truck rolls, and incident length all impact operating margin.
Solution Overview
Each ATM ships with an R2011 preconfigured for secure uplinks and remote operations. Transactions traverse an encrypted tunnel; management paths are controlled and auditable. RCMS provides the fleet view and change workflows.
- Dedicated backhaul: Use 4G/LTE as primary or backup; add Ethernet WAN where available for dual-path designs.
- Encrypted tunnels: Establish IPsec/OpenVPN to your data center or payments concentrator; keep routes predictable and isolated.
- Dual-SIM resilience: Two carriers reduce single-network exposure; failover policies keep the ATM reachable.
- Segmentation & filtering: Apply VLANs and firewall rules so transaction flows and management traffic remain scoped.
- Remote operations: RCMS templates, monitoring, and scheduled updates make configuration and firmware rollouts repeatable.
- Operational telemetry: Signal, uptime, and data-use views help NOC teams spot issues early and shorten MTTR.
Expected Customer Outcomes
What success looks like for the key stakeholders (Head of ATM Operations, Payments/Network Security Lead) and the secondary stakeholders (Field Service Providers, Managed Network Partners)
- Head of ATM Operations: Higher availability across mixed venues; predictable failover and a single dashboard for health and usage.
- Payments/Network Security Lead: Encrypted, segmented paths with clear change history and policy control.
- Field Service Providers: Fewer site visits; remote access for triage, config checks, and controlled restarts.
- Managed Network Partners: Standardized edge design per site; simpler onboarding and faster incident isolation.
