Overview
Overview
The Symmetricom® TimeProvider™ 2700 is an IEEE 1588 Precision Time Protocol
(PTP) Grandmaster scaled and optimized for deployment to support small cells and
to meet the stringent phase timing and synchronization requirements of 4G/LTE
networks.
With an integrated GNSS receiver (GPS or GLONASS) the TimeProvider 2700
meets requirements of the ITU-T G.8272 standard for a Primary Reference Time
Clock (PRTC). It can operate in Synchronous Ethernet (SyncE) networks, and
supports from 8 to 64 PTP clients. The TimeProvider 2700 offers the optional
capability to accept a PTP input or T1/E1 input to complement and backup the
GNSS signal. Additional output capabilities allow it to support legacy frequency
timing applications.
The TimeProvider 2300 Advanced Boundary Clock accepts PTP input. It can
operate in Synchronous Ethernet (SyncE) networks, and supports from 8 to 64 PTP
clients. The TimeProvider 2300 offers the optional capability to accept T1/E1 input
to complement and backup the PTP input signal. Additional output capabilities allow
it to support legacy frequency timing applications.

Chapter 1 Overview
Overview
Software Options
The TimeProvider 2300/2700 also provides several software options. An activation
key is required to access these options, which include:
Greater client capacity: Client capacity can be increased from 8 to 16, 32, or
64, clients, allowing network engineers to design for capacity they need today
and be protected for increased requirements in the future.
GPS and GLONASS: The basic model of the TP 2700 uses GPS and GLONASS
signals as its primary reference. A software license option adds support for
concurrent GPS and GLONASS signals, adding another dimension of sync
protection for your network. Use of GLONASS requires different antennas than if
only GPS is used. (The TP 2300 does not have GNSS.)
PTP Input: Employing PTP distributed over the backhaul network provides a
backup to GNSS, allowing the oscillator to hold accurate timing longer than
otherwise possible. The PTP client option, enabling a boundary clock function,
includes advanced algorithms that compensate for network
asymmetry-particularly important for LTE-TDD and LTE-A networks with tight
phase synchronization requirements. The PTP Input License is included as part
of the TP 2300 base model.
SyncE Output: Synchronous Ethernet provides a stable frequency reference for
Ethernet networks. This software option enables SyncE on the Ethernet output
port, operating in conjunction with PTP output on the same port. SyncE on the
Ethernet input port is supported in the basic configuration.
E1/T1 Input/Output: The E1/T1 software option activates this interface for
frequency synchronization of equipment using this established reference for
timing.
PPS+TOD RS422 Output: Commonly used in test equipment and other devices,
this option enables an RS422 port for Pulse Per Second (PPS) and Time of Day
(TOD) signals
See TimeProvider 2300/2700 Part Numbers, on page 267 for part numbers for all
available options.
Activation keys are associated with the serial number of the device on which the
keys are stored and travel with that device. The user must manually enter key(s)
with CLI commands to gain access to the licensed software options.
Security Features
The TP 2300/2700 was designed to provide a high level of security on the Ethernet
ports. The protocols running on the unit run from behind an internal firewall. This
allows access to the UDP ports to be limited or completely inaccessible by other
systems.
098-00564-000 Revision A3 – July, 2013 TimeProvider 2300/2700 User’s Guide 25
Chapter 1 Overview
Physical Description
Each of the service ports only allows PTP, ICMP, and IGMP. The MGMT port allows
user-configuration of the firewall, which includes ICMP, FTP, SSH, telnet,
HTTPS/HTTP and SNMP.
The ETH1 and ETH2 service ports do not support routing protocols between the
ports. This prevents a malicious attack on the ETH1 port (network 1) to be used to
send a malicious attack via the ETH2 port (network 2) or vice-versa.
The ETH1 and ETH2 service ports also include a hardware traffic limiter. If the
number of packets per second exceeds the limit, the unit will generate an alarm
indicating excessive traffic is being seen. This could be an indication of a malicious
attack or it could also be a large number of clients requesting service from the
server. The system will drop packets received in excess of the limit. Packets
received below the limit will be handled normally.
If the ETH1 and ETH2 service ports do come under attack, only the ports under
attack will be affected due to the system's architecture. The MGMT port will
continue to provide all management facilities for the system during this type of
attack. To minimize system resource usage and deter denial of service attacks, the
system is configured to allow a maximum ICMP ping request rate of 16 per second.
Conclusions
The TP 2300/2700's architecture isolates functional areas such as user
interfaces and output signal generation to minimize the possible corruption of
time and frequency outputs.
Only service-specific UDP protocols are enabled.
From a system security perspective the TP 2300/2700 provides the highest level
of security while providing very accurate time and frequency outputs. However, it
also requires that the user implement best-practice security safeguards in their
networks for the most robust levels of security.
Physical Description
The TimeProvider 2300/2700 consists of a 19-inch (48 cm) rack mount chassis,
plug-in modules, and hardware.
Note: The TP 2300/2700 comes equipped with 19-inch rack
mounting brackets. 23-inch (58.42 cm) rack mounting adapters are
also available as a separately ordered item. 21-inch (ETSI) rack
mounting adapters are available as a separately ordered item.

Communications Connections
The TimeProvider 2300/2700 can be controlled through either the Ethernet
Management port or the serial port.
Ethernet Management Port
The Ethernet Management port on the front panel of the TimeProvider 2300/2700 is
a standard 10/100/1000 Base-T shielded RJ-45 receptacle. To connect the
TimeProvider 2300/2700 to an Ethernet network, use a standard twisted-pair
Ethernet RJ-45 cable (CAT5 minimum).
Serial (Craft) Port
The serial port connection is made through a DB-9 female connector on the front
panel of the TimeProvider 2300/2700. This port, which supports a baud rate of
57.6k (57600-8-1-N-1), allows you to connect to a terminal or computer using a
terminal emulation software package. When connecting to this port, use a shielded
serial direct connect cable.
Figure 1-5 shows the DB-9 female connector for the serial port.
