Item
Description
Functional
versions
The
GSCC is available in the following functional versions: N4 and N6.
Differences
Packet
performance specifications differ between the N4GSCC and the N6GSCC. For details, see Packet System Performance.
Substitution
The
GSCC boards of different versions cannot directly substitute for each other. If the GSCC of a later version needs to substitute for the GSCC of an earlier version, the NE software needs
to be upgraded accordingly.

Function
and Feature
GSCC
Basic
functions
Performs
the service configuration function and service grooming function, monitors the service performance, and collects information about performance events and alarms.
Interfaces
Provides
the 10M/100M Ethernet port, which is used for communicating with the NMS. The Ethernet port is accessed through the AUX.
Provides
the F&f interface, which is accessed through the AUX and is used to manage the COA.
Provides
one 64 kbit/s synchronous data port F1, which is accessed through the AUX.
Provides
the RS232 OAM interface, which is used for connecting a PC or workstation, and supports the remote maintenance by using a modem that uses the RS232 DCE interface. The OAM interface
is accessed through the AUX.
DCC
communication
Processes
a maximum of 160 DCCs (D1–D3). In this manner, the link is provided for transmitting the NM information.
Overhead
processing
Processes
the E1, E2, F1, and serial1–serial4 bytes.
Clock
function
Provides
the RTC.
Supports
the high-precision clock synchronization feature, and complies with the IEEE 1588 V2 protocol. The N4GSCC receives the time information through interfaces S1–S4 of the AUX. The S1,
S3 and ALMI4 interfaces receive the first channel of time information, and the S2, S4 and ALMI4 interfaces receive the second channel of time information.
Alarms
and maintenance features
Supports
service performance monitoring and collects information about performance events and alarms.
Provides
16 alarm inputs and four alarm outputs through the AUX.
Provides
one 4-output alarm cascading port through the AUX.
Controls
the four cabinet indicators through the AUX.
Supports
intelligent fan speed control and manages the fan alarms.
Supports
simulation package loading and diffused loading.
Supports
the function of detecting whether a packet data board is in position.
Power
supply management
Supports
the monitoring of the –48 V or –60 V power supply.
Supports
the in-service check function for the PIU board and supports the failure check function for the lightning protection module of the PIU.
Protection
schemes
Supports
the 1+1 Hot Backup for the SCC Unit. When the active board is faulty, services are switched to the standby board automatically.
NOTE:
If
GSCC boards are used in packet systems, two N4GSCC/N6GSCC boards of the same version need to be configured in 1+1 backup mode.
Packet
function
The
N4GSCC and N6GSCC support the packet function.
