Lawful Interception Appliances for Fast, Compliant Deployment
Dedicated hardware with pre-integrated LI software. Deploy it quickly, operate it securely and remove it without long-term changes to your network.
Lawful interception appliances are dedicated hardware units with pre-integrated LI software that capture, mediate and hand over intercepted traffic. ICS builds its lawful interception appliances for plug-and-play deployment in short-term operations, legacy migrations and specialized scenarios. They are easy to deploy, operate and remove, and they scale with the task.
关键事实
- Dedicated hardware: optimized appliances with pre-integrated lawful interception software.
- Plug-and-play: installed quickly, operated securely, removed without long-term network changes.
- Two products: the Temporary Lawful Interception Box and the PSTN/ISDN to SIP Converter.
- Scalable: small, medium and high-capacity configurations.
- Standards-aligned: secure handover to law enforcement, and VoIP interception per ETSI TS 102 232-5.
- 经验: more than 20 years in telecommunications and LI, with multiple BNetzA acceptances.
When do lawful interception appliances make sense?
Permanent interception infrastructure is not always practical. Some situations call for a self-contained unit that works from day one and leaves no footprint.
- Short-term operations: ad-hoc orders, temporary projects and temporary networks.
- Pilot networks and market entry: new services that must be interception-ready before permanent LI is in place.
- Legacy migrations: PSTN and ISDN networks moving to SIP, where interception must continue throughout.
- Specialized scenarios: network segments or sites where a full LI stack is not economical.
In Germany, the TKÜV exempts operators of systems with no more than 10,000 connected users from keeping permanent interception facilities. The exemption does not remove the duty to implement a lawful order when one arrives. A temporary appliance is a typical answer.
Our lawful interception appliances and matching software
Two purpose-built appliances cover the most common needs, and ICS software completes the chain.
01
临时合法截取箱
A rapid-deployment unit for VoIP, IP and messaging interception in pilot networks, temporary projects and ad-hoc operations. It combines capture, mediation and secure handover in small, medium and high-capacity sizes. 了解更多
02
PSTN/ISDN 至 SIP 转换器
Bridges legacy circuit-switched PSTN and ISDN to SIP. It converts signaling and media so that VoIP interception per ETSI TS 102 232-5 continues during migration. 了解更多
How does an appliance deployment work?
1
Assess
ICS reviews the network, the services in scope and the legal requirements.
2
Size
The team selects a predefined capacity configuration and the required interfaces.
3
Install
The appliance is placed at a suitable point in the network and connected.
4
Configure and test
Targets are set up on the basis of valid legal orders, and handover to the monitoring facility is tested.
5
Operate and remove
The appliance runs as long as needed and is then removed without long-term changes.
Appliance or permanent LI infrastructure?
The right choice depends on duration, volume and network plans. Our article on temporary LI boxes vs permanent systems covers the trade-offs in detail.
| 标准 | LI appliance | Permanent LI infrastructure |
|---|---|---|
| Time to operation | Short, hardware and software come pre-integrated | Longer, planned integration project |
| Typical use | Short-term orders, pilots, migrations, small networks | Ongoing interception across the whole network |
| Network changes | Minimal, removed without long-term changes | Permanent integration into core and IT systems |
| Capacity | Predefined small, medium and high-capacity sizes | Designed for full network load |
| Management | Standalone or linked to an existing LIMS and mediation | Central LIMS and mediation platform |
| Exit | Unplug and remove | Decommissioning project |

常见问题
What are lawful interception appliances?
Lawful interception appliances are dedicated hardware units with pre-integrated interception software. They capture the traffic of targets named in a legal order, mediate it and hand it over securely to law enforcement. ICS offers a temporary lawful interception box for VoIP, IP and messaging, and a PSTN/ISDN to SIP converter for legacy voice networks.
When is a temporary LI box better than a permanent system?
A temporary box is often the better choice when interception is needed quickly, for a limited time or on a small network. Examples are pilot networks, market entry, migrations and ad-hoc orders. Permanent infrastructure suits ongoing interception across a large network. The box can also extend an existing LI setup.
Do small operators in Germany need interception capability?
Under the TKÜV, operators of systems with no more than 10,000 connected users do not have to keep permanent interception facilities. They must still implement lawful interception orders when they receive them. A temporary box from ICS, planned in advance, can be activated quickly when an order arrives and removed once it ends.
PSTN/ISDN 到 SIP 转换器有什么作用？
The converter bridges legacy circuit-switched PSTN and ISDN connections to SIP. It transforms signaling and media into SIP, so interception platforms can capture voice and multimedia sessions as VoIP per ETSI TS 102 232-5. Operators can keep intercepting while they migrate to IP voice.
Can ICS appliances connect to existing LI systems?
Yes. ICS appliances run standalone or as an extension of an existing lawful interception setup. ICS tailors protocols, capacity and integration with mediation platforms, management systems and agency interfaces. Operators can add capacity or cover a new network segment without replacing what already works.
