LT Application and Access Network
Note 1:
For LT applications in general it is recommended to use the device kit
PEB 24911 / PEB/F 24902 (Quad IEC DFE-Q/AFE), which offers the same
function for four metallic lines. In some special configurations, however, (e.g.
line cards with 6 lines) it might be more cost effective to use the IEC-Q. In the
configuration below system integration on existing boards is sketched.
An LT configuration with up to 8 IEC-Qs can be built with an EPIC® and two IDEC®s. The
EPIC® controls the C/I-channel, the B-channel slot assignment and the Monitor channel
handling. The IDEC® is a HDLC-controller for four independent D-channels.
