SP505 Datasheet, PDF (23/35 Pages) Sipex Corporation – WAN Multi-Mode Serial Transceiver

The SP505 was externally tested by TUV
Telecom Services, Division of TUV Rhein-
land, and passed both NET1/2 and TBR2
requirements. Test reports (NET2/052101/98 for
NET1/2 and CTR2/05101/98 for TBR2) can be furnished
upon request.
Please note that although the SP505 ad-
heres to NET1/2 testing; any complex or
unusual configuration should be double-
checked to ensure NET compliance. Consult
factory for details.
