Features
(continued from page 1)
Mapping/Multiplexing Modes (x28/21)
I
Maps DS3 clear channel or framed signal into STS-1
or TUG-3.
I
Maps T1/E1/J1 into VT/TU (including DS1 into
TU-12).
I
Supports asynchronous, byte-synchronous, and bit-
synchronous mapping.
I
Supports UPSR applications via the dedicated ring
interface and an external tributary selector.
I
Supports all valid T1/E1/J1 multiplexing structures
into STS-1 and STS-3/STM-1.
— STS-3/STS-1/SPE/VTG/VTx
— STM-1/AU-3/TUG-2/TU-1x/VC-1x
— STM-1/AU-4/TUG-3/TUG-2/TU-1x/VC-1x
I
Allows grooming of VTs/TUs in granularity of TUG-2s
within the STS-3/STM-1 signal.
I
Supports J2 trace Identifier monitoring/insertion.
I
Configurable VT/TU slot selection for DS1, E1, J1
insertion and drop.
I
Automatic receive monitor functions include VT/TU
RDI-V, REI-V, BIP-2 errors, AIS-V, LOP-V.
I
Complies with GR-253-CORE, GR-499, ITU-T
G.707, G.704, G.783, T1.105, JT-G707, ETS 300
417-1-1.
M13 Features
I
Configurable multiplexer/demultiplexer for 28
DS1signals, 21 E1 signals, or 7 DS2 signals to/from
a DS3 signal.
I
Operates in either M23 or C-bit parity mode.
I
Provisionable time-slot selection for DS1, E1, and
DS2 insertion or drop.
I
Full alarm monitoring and generation (LOS, BPV,
EXZ, OOF, SEF, AIS, RAI, FEAC, P-bit and C-bit par-
ity errors, FEBE).
I
HDLC transmitter with 128-byte data buffer and
HDLC receiver with 128-byte data FIFO for the C-bit
parity path maintenance data link.
I
DS3, DS2, DS1, and E1 loopback and loopback
request generation.
I
Complies with T1.102, T1.107, T1.231, T1.403,
T1.404, GR 499, G.747, and G.775.
DS3/DS2/DS1/E1 Cross Connect
I
Highly configurable interconnect for up to 28 DS1 or
21 E1 signals to/from the framer, external pins, M13,
or VT mappers.
I
Also supports up to seven DS2 signals to/from the
external pins or M13.
I
Sources may be broadcast or looped back or routed
to/from a test-pattern generator or monitor.
I
Any DS1 or E1 channel may be routed through the
jitter attenuator.
I
DS3 may be configured for the M13 to interconnect
with the SPE, or external I/O to interconnect with the
M13 or SPE.
Jitter Attenuation
I
PLL-free receive operation using built-in digital jitter
attenuator (in VT/VC mode or M13 mode).
I
Configurable to meet jitter and MTIE requirements.
PDH Interfaces
I
One DS3, 7x DS2.
I
28/21 framed or unframed DS1 or E1 interfaces.
I
One additional dedicated protection channel for DS2/
DS1/E1.
T1/E1/J1 Framing Features (x28/21)
I
28/21 T1/E1/J1 channels.
I
Line coding: B8ZS, HDB3, ZCS, AMI, and
CMI (JJ20-11).
I
T1 framing modes: ESF, D4, SLC
-96, T1 DM DDS,
