Circuit Pack Description 7
Purpose of Circuit 7
The OC48 Transmitter (OC48 TRMTR A/D) circuit pack provides a high speed
interface between sixteen 155.52 Mb/s electrical signals and the outgoing OC-48
optical signal (2.5 Gb/s).
The 739B2, 739C2, 739E_, and 739J2 OC48 TRMTR A/D circuit packs are used
in bidirectional ring applications and are compatible with Release 3.0.1-ADR and
later software. The 739J3 OC48 TRMTR (A/D 1.5 LBA) circuit pack is used in
bidirectional ring applications and is compatible with Release 5.0.1-ADR and later
software. The 739R2 OC48 TRMTR (A/D 1.5 LBA W1) and 739S2 OC48 TRMTR
(A/D 1.5 LBA W2) circuit packs are used in bidirectional ring applications and are
compatible with Release 6.0.0-ADR and later software. The 739E_, 739G_, and
739H_ circuit packs are used in DWDM applications and are compatible with
Release 7.2 and later software.
The 739B4 OC48 TRMTR (A/D 1.3 STD) circuit pack is a cost-reduced version of
the 739B2 OC48 TRMTR (A/D 1.3 STD) circuit pack and is compatible with
Release 7.0.0-ADR and later software. The following OC48 TRMTR circuit packs
have an STS-1 time slot assignment capability that allows STS-1
cross-connections and are compatible with Release 7.0.0-ADR and later
software.
