Feature Summary
The following is a summary of the features provided by the CX28560:
2047-channel, full-duplex link layer controller for synchronous applications.
32 full-duplex physical interfaces (i.e., ports) with independent clock rates.
General purpose HDLC (ISO 3309) is supported.
Hyper-channels and sub-channels are supported.
The CX28560 implements 32 serial ports that are individually programmable
to operate either as conventional serial ports or TSBUS serial ports. Both
operational modes allow the input/output data stream to be configured as
channelized or unchannelized bit streams. Clock rates may be as high as 52
MHz.
HDLC/SDLC
HSSI
ISDN D-channel (LAPD/Q.921)
X.25 (LAPB)
Frame Relay (LAPF/ANSI T1.618)
Inter-System Link Protocol (ISLP) support
LAPDm support
ATM/SMDS DXI
Transparent unformatted mode
Point-to-Point-Protocol (PPP)
Multi-Link-Point-to-Point-Protocol (MLPPP)
Applications that require hyper-channeling:
Sub-channeling mode
– ISDN Primary Rate Interface (PRI)
– ISDN Primary Rate Adapter (PRA)
– Fractional T1 (FT1)
– Fractional E1 (FE1)
– Fractional Nx64K
– SONET/SDH/PDH paths connected via TSBUS:
– Multiple lines multiplexed to 1 port:
– Each channel can be programmed to either use a complete DS-0 time slot or
– Applications that require sub-channeling:
mask any subset of a time slot. A signal mask is defined per-channel basis
that has an enabled bit per time slot. The mask bit dictates whether the
whole DS-0 or part of it is enabled.
