Product Description

Juniper Networks CTP Series Circuit to Packet Platforms provide the advanced technology and features required to reliably transport time-division multiplexing and other circuit-based applications across next-generation IP/ MPLS networks. The CTP Series has the field-proven flexibility, performance and reliability required for circuit applications. The CTP Series technology includes many advanced clocking options and per-circuit buffers to enable end-to-end timing and the removal of jitter to create a pseudowire across the IP/ MPLS network. The CTP Series enables customers to connect digital and analog voice applications easily and reliably across the IP network using circuit emulation over IP, bringing them the advantages of converged multiservice IP networking without the complexities and cost of upgrades required for VoIP. The CTP Series bridges the legacy and IP world and provides many unique features that enable cost reduction by eliminating point-to-point circuits and convergence of all applications onto one IP/MPLS network.

With the ongoing deployment of IP networks, the efficiency and cost-savings gains of IP are being realized for a variety of applications and functions. Largely left out of this evolution have been the circuit-based applications such as time-division multiplexing (TDM) leased line and voice private branch exchange (PBX) connections, serial encryption connections, and analog and digital radio systems networking, because their synchronous transport requirements are not addressed by a packet-based network. The Juniper Networks CTP Series Circuit to Packet Platforms enable customers to connect these circuit-based applications easily and reliably across the IP network, bringing them the advantages of converged multiservice IP networking.

The CTP Series includes the Juniper Networks CTP151, CTP2008, CTP2024, CTP2056 Circuit to Packet Platforms, and the Juniper Networks CTPView Network Management System. The products are designed for government agencies, enterprises and service providers running circuit-based applications and range in size, port capacity and redundancy options.

Features and Benefits:

Key features and benefits of the CTP Series Circuit to Packet Platforms include the following.

Feature	Feature Description	Benefit
Software circuit provisioning	EIA530, RS-232, V.35, 4WTO, T1, and E1 circuit types are software configured including the line encoding, clocking, rates, and IP settings.	The network quickly fulfills new and changing end user requirements without deploying excess hardware.
Scalable product family	A family of four CTP Series Circuit to Packet Platforms provides different port densities. Products can address the requirements of small remote sites through large central network hubs.	Network designers control costs by selecting the CTP Series Circuit to Packet Platforms most suitable for the site when considering circuit quantities and anticipated growth.
CTPView Network Management System	Secure, multi-user, web-based network management system provides network monitoring, circuit provisioning, IP performance reporting, database backup, and circuit troubleshooting tools.	Managers quickly deploy circuits and services while proactively monitoring the network. IP performance reports provide detailed information on IP network jitter, delay and packet loss. Circuit troubleshooting tools include integral BERTS and loops to facilitate quick trouble resolution.
Multiple system and circuit clocking solutions	CTP Series Circuit to Packet Platforms are designed to use multiple external clocks as monitored and prioritized system references. Circuits are configured to use the system clock, external circuit timing, or to adaptively recover clock information from the remote port when required by the application or when no reference is configured.	Circuit reliability is improved since ports and systems are configured with the clocking solution that is most appropriate for the particular application.
Auto switch	The status of the CTP Series circuit ports is monitored, and the circuit is automatically switched to an alternate local or remote port when a failure is detected.	Network and circuit reliability are increased when the circuits are automatically restored to alternate locations and equipment in the event of an equipment, site or network failure.
Packet protector	Redundant packets are created and transmitted to the IP network and then processed by the receiving CTP Series.	Circuit quality and reliability are increased when IP connections experience significant packet loss caused by bit errors.
Autobaud	The input timing leads are monitored, and the circuit rate is automatically changed at both ends of the network if a rate change is detected.	Flexible rate agility enables immediate and automatic provisioning changes.
Loops and BERTs	Each CTP Series port supports interface and network loops and the ability to generate and monitor a bit error rate test with up to nine BERT patterns selectable.	Support for standard circuit troubleshooting tools that are built into the CTP Series help to quickly isolate network, circuit or cable problems.
Layer 2 Serial-toEthernet IP aggregation	The CTP Series Circuit to Packet Platforms can aggregate layer 2 traffic from serial interfaces onto a Fast Ethernet or Gigabit Ethernet interface. Layer 2 protocols supported are Frame Relay, PPP and Cisco-HDLC. Each CTP Series port is connected to a different VLAN.	The ability to aggregate layer 2 traffic on the CTP Series from multiple serial interfaces reduces the router interfaces needed for low-speed IP aggregation.
Port mirroring	The CTP Series is able to port-mirror any transmit or any receive up to 10 local or remote destinations.	Port mirroring minimizes the bandwidth required to send the same traffic to multiple sites across the network. It enables easy monitoring for troubleshooting circuit problems. Port mirroring enables the replication of data to multiple local or geographically dispersed locations.
Analog voice—4WE&M	The CTP Series supports analog 4WE&M type I, II,and V interfaces with software selectable transmit and receivelevel adjustments per interface.	The ability to support analog 4WE&M interfaces allows the CTP Series Circuit to Packet Platforms to offer another PBX trunking option. The 4WE&M interface can also be used for radio interfaces with push-to-talk requirements.
Analog voice—2WFXS	The CTP Series supports analog 2WFXS loop start, ground start, and PLAR modes with software selectable transmit and receive-level adjustments per interface.	The ability to support analog 2WFXS interfaces allows the CTP Series Circuit to Packet Platforms to offer 2-wire voice extensions over IP for remote phones, remote central office or PBX equipment.
Analog voice—2WFXO	The CTP Series support analog 2WFXO loop start and ground start modes with software selectable transmit and receive-level adjustments per interface.	The ability to support analog 2WFXO interfaces allows the CTP Series Circuit to Packet Platforms to offer 2-wire voice extensions over IP to remote phones, or remote central office or PBX equipment.
IRIG-B	The CTP Series supports an inter-range instrumentation group time code (IRIG-B) signal to be transported through an IP network. IRIG-B encodes day of year, hour, minute, and second data on a 1-KHz carrier frequency, with an update rate of once per second.	Provides the ability to support IRIG-B transport over the IP network with options to configure direction, output high and low levels, and data range per interface.
